Welcome to Marriage Builders, waaw...
For the life of me, I can't think of how to really shorten your screen name.

In your very first paragraph you captured why the rule of happiness doesn't work...and how we can't really make our spouses happy.
We certainly contribute to their unhappiness.
The moral of happy isn't moral...or real. There isn't "when we get through this, then I'll be" because that's fantasy. You don't know what you'll feel until you get there.
We are made to experience the right here, the right now. Everything we do, think, feel, believe and perceive only happens in our choices right now.
What you hear from her isn't the truth (future fact)...it's her truth. What she believes...you can believe differently. I wonder what was in it for you to choose to not believe differently?
She believes if only this, then I will feel. Good to know that's fantasy. Not reality. Best way to understand your partner is to listen and repeat...to confirm or clarify that you heard them correctly...
"I hear you saying you're choosing not to be happy right now, but will later, after you get a job (fill in the blank), is that correct?"
When you get clear on not changing her feelings, her stuff...then you step up to partnering from parenting.
Next, hear her wishes as wishes they are...and know your wishful statements, too. Be clear on your stuff--own your thoughts, feelings, perceptions, beliefs...don't make them fact.
You hear her as critical, demanding...and yet you say she has a progressive and declining health issue. Is there an eventual resolution to it? Is there not? Not to excuse...to know and understand...most of what we demand/criticize in others, we are really doing to ourselves.
You can take it as about you...and make it a battle. Or you can strive first to understand, then be understood. Your choices are half the marriage.
You've greatly harmed your marriage. "I of course have no say in all of this because In another attempt to make her happy I gave her complete control of everything years ago."
You've had responsibility for half the marriage all along. You cannot give that responsibility away. You can avoid conflict, pacify, lie and manipulate...and you will still be responsible emotionally, financially, physically and mentally.
Don't buy your own fantasy, a defective coping skill...a cop out. Same for finances...you take the steps necessary to protect The Marriage...even when you don't FEEL like protecting her.
What I hear you saying about her the most is that she doesn't own her choices...and I don't hear you owning yours...when you do, the fantasy dissolves.
I chose to marry my wife. I chose to have a child with her, though I feared financially about the timing, and we managed to make it through to owning our own home, debt free. Then I chose to sell it. I chose to believe I could make her responsible for everything in the marriage, so I could feel blameless.
I lie by omission to keep things smooth...I listen to fix, not to know...I want to change my wife, her stuff, and then mine will change and I will be happy.
What if you're only doing the same thing? "If only my wife would be happy, then I would be happy." ?
Our partners are our reflections, as well as being whole, separate and equal individuals. That's pretty tricky, I think; complex and not easy. Simple. Not easy.
What if her anger is hers? Not about you? What if feeling the anger is okay and acting it out isn't? What if each time you did not say "that's unacceptable" when she defined you, yelled, snarked or degraded you, you were attacking your marriage? Would you have kept doing it?
I don't think so. Your healthy boundaries go with you...whether the marriage survives (or thrives) or not. These same choices you make to please (pleasing is disrespectful) continue, so does any future relationship you have...you'll end up seemingly in the same place, same lesson.
Learn now...take this opportunity to change your choices...remove blame from your marriage, see your wife as she truly is...separate and equal...and get rid of the happy moral and insert what you most crave...respect, consideration, acceptance, understanding...honesty.
Get really honest...read the articles, letters, books here on this sight and understand the four rules of marriage, how conflict is BETTER than withdrawal (few words to soothe) because humans connect in conflict, as well. And how it's not about being right...
it's about being married.
Healthy boundaries...you may be calling her names, defining her, in your head, not out loud...because you're permitting yourself to do that, you permit her to do that to you..revoke that permission. "Name calling is abusive. I won't stay present if you continue." Then follow through if she does...and if she doesn't, thank her for respecting your boundary.
That goes for profanity, AOs, SDs...learn about them, eliminate them from yourself and you will stop staying present for them. When you do remove yourself and your baby as a boundary enforcement, state what you're doing, why you're doing it, and when you will return to the discussion.
First time, usually 20 minutes for the chemicals released in your brain to dispurse...if she continues, remove for two hours...
Beware, though, your conditioning...if you choose not to listen and repeat, "I just heard you call me stupid, is that correct?" because you can hear what she didn't say..."I think you selling the house was stupid" is not calling you stupid.
And know your accomplishments...because it sounds like what you once knew, you don't remember now, either...
Together, you both have married, finished college, created a human being, bought a house, paid off a house, sold a house, gotten and held jobs (and it takes time to work upwards in the payscale, regardless of the field), been there with each other, and have learned a lot together and separately about marriage and yourselves.
Learning what you won't tolerate (any longer) is learning. When you change, the dance changes.
Sounds to me like FS is one of her top ENs...and FC is one of yours. That doesn't make her good with money or you good with kids, either. Means that when she acts from love towards you, like Affection, you get a love deposit. When you get a raise, she gets a deposit. Get to know your ENs, your LBs...because resentment can distort and obsess on what you lack right now...instead of what is abundant in your life.
About criticism...every twitch of your muscles...two things...one, you're deeply angry at yourself for staying present for the abuse (your choice), and two, you also hurt for knowing what she does to you, she does also to herself...
She doesn't deserve that treatment, does she?
So check yourself (all you have in your control)...you experience her as mean to you...are you mean to yourself? Is staying present for abuse punishment to you? A sacrifice? Your way to avoid conflict, not escalate, pacify in some way? Do you deserve that treatment--what you're doing to yourself?
Are you going to lead by example or fault by passive-aggressiveness? Are you going say, "I don't know if I can survive our marriage" a truer statement, maybe, than asking if the marriage is viable.
It's your marriage. It's alive...you're still half of a team, even when your partner seems like your enemy. Clear up your stuff...to see clearly...go for clarity...set your own goal...to have a rockin' great marriage with your partner...and see where enforcing healthy boundaries is an act of real love...and how you have been reacting to your fear, just as she has, so you both share so much in common.
Be there for one another and yourselves.
That's marriage.
Get to know what is verbal abuse "The Verbally Abusive Relationship"...so you can see, understand and define your boundaries...and you'll be surprised at how you, too, have acted abusively...so you can stop.
Learn to share, listen and repeat, stay present and intimate in healthy ways...to ask for what you want as yours...not about getting her to feel happy, remorseful; to stop her from hurting you.
You may be hearing her threats as boundary enforcements...if you do this, I'll do that. With healthy boundaries, yes, you have predetermined progressive enforcements...not SDs...which is what this is...so learn the difference. You'll find abuse within the all or nothing; or what sounds like a simple request requiring you to do something she wants, when she wants it and in the way she wants it.
I was your wife, btw...not you. I loved my DH hard and long and beat him down, too...wasn't healthy, wasn't what I really wanted, and when I almost lost our marriage, I woke up. I'd like you to see your 20th anniversary and three boys someday...with your wife...knowing you were a team, all the way, even when it didn't feel like it.
We're still in it together.
You don't make creating a child together up to anyone...he/she is a gift to the world...not a mistake, not a wrong.
She chose to have the child too. Know this. It's not the issue. Listen and repeat, "I hear you wishing our life was different right now, saying you didn't want our child back then, is that correct?" Calmly, assertively, for clarity. Really hear if it's wishful (fantasy), fearful, blame-shifting...what...don't assume, read between the lines...restate. Acknowledge, not fix. Not amend.
Hear where you define her...can be really sneaky.
Hold yourself to stating, not demonstrating...when you fear, state your fear...it's yours. It's valid. Doesn't mean she's frightening...means you feel fear. Don't react to it.
Take back your half of the responsibility for the finances...get creative with ownership...maybe the joint account with both your direct deposits is just for household bills...all of them...shared expenses...total it up, split it in half and deduct that from your net...and make your own account for what's left over for it. Same for hers. Share your ideas of what is a household bill and what's discretionary spending...would you have an issue with her endless soda (a DJ btw) if she bought it from her own account?
Does it advance her illness? Are you physically well now, btw?
Share your goals with each other and the goals for your marriage...enforce your boundaries progressively, not reactively, and get to know your partner today...stop taking her choices as threats...they are her choices.
Stop assuming why she says/does what she says/does...focus on actions, on reality...which is only you choose...you make your choices...you are free to base them on her possible response...but that's all assumption...base them on your own integrity...ferret out your own controlling ways, which are fantasy...because you're feeling victimized and controlled.
Don't let silence speak for you...it says nothing and betrays yourself. Then you see her as betraying you. The dance continues. Free yourself. And change the way you experience your marriage.
