Lonestardad,
Haven't been on this site much, too much work this last month. Been here a long time and I think there are some things you really need to consider and address.
First, you need to go to plan B before you run out of love for your W. If you run out of love, there is little chance for the marriage to recover. Oddly, it is the BS that has to do the heavy lifting during recovery and it is very difficult,but more so if you don't love your W.
Second your W is still in her affair and plan B protects you from that and the pain she can and will inflict until she gets out of here affair.
Please understand plan B is about protecting YOU! It is not about forcing the WS to do anything. You must preserve the love you have left OR you might as well file right now. Your plan B letter should reflect this thinking and you are being very foolish not to have responded to Pep and let her and others see your first attempt at writing this letter.
The reason the folks here need to see it is simple. Rarely does a BS truly comprehend the purpose of plan B and therefore the letter is rarely what it should be.
You said
I know I need to start working on my self-esteem because my WW crushed it last year and sent me spiraling into a depression after 4-5 weeks of denying the affair and me going crazy. I know the things I need to do, but it's hard getting started and I have few if any close friends. My WW and I were always the closest friends in our marriage before the A.
I understand your feelings but you are looking at this all wrong.
You are the one taking care of the family. You are the one fighting for the family unit. You are the one that has been faithful his vows. You are the one that is bringing stability to your kids. You are the one doing all of this while under great duress.
You should be proud of what you have done and are doing. You should now realize that you don't need your W to take care of the kids, cook for them, guide them, nurture them, and rear them. You should by now understand that you need to protect yourself and your family.
It is time for a perspective change young man. Go see a lawyer and find out what you can and cannot do. I seem to recall that Texas does not have legal separation, so you may have to file for divorce to protect your assests and your children from their mother taking them. Look into it.
BE PREPARED!
STrongly consider plan B and make the appropriate preparations. It is probably time to be out of plan A, especially if you are losing your love for your W.
In short Lonestardad, it is time to "cowboy up" and realize you have great value to your children, you have great value to yourself, and that have shown that you are a very tough man that has handled great pain and kept on going.
Reread about plan A and plan B, and prepare yourself for the worst, hope for the best and play it down the middle.
You can do this and the folks here will help you...GET A PLAN.
God Bless,
JL
