Fresh Pain,
I am so sorry for what is happening, and I hate to be one that dumps on you, but I believe if something is not working, then you need to change it.
Your wife has no consenquences for what she has done. It looks like there have not been any for each instance she has strayed.
If she cared what you think, she would not be going to a friends house and coming home early in the morning, and she would not stay away from home after work.
It looks like the affair is still going on right in front of you. If you continue to believe her when she makes excuses, she will continue to do what she is doing.
She is trying to twist what is going on, by calling you controling. This is a mockery of what is happening.
HOWEVER, your choices are to stay with her, and try to work it out, or to leave.
If you stay, you must use all the tools you have to end her affair, because there is no chance for your marriage while she continues.
So, you need a plan. You need to run the plan no matter what she says, or what she does. She will use every threat, and ever trick she can think of to stay in the affair. Like an addict, for that is what she is. Affairs have a chemical element to them, and her brain is addictec to the high she gets from contact. Unless you can help her break contact, she will remain addicted, and the ruin of your family will continue.
I suggest you call the Harleys for counseling, so that they can help you put together a plan to save your marriage. We are fellow travelers, and some of the best on MB have responded to you, but I believe you could really benefit from getting professional help.
As far as being controling. You can't make her do anything, but then you don't have to stay either. You simply decide what you have to have from her to not kick her out, and if she doesn't do it, she goes, or you go. She is free, but so are you. You can make it about you, not her. You explain that this is killing you, and that you can't stand it any more. If she says you are trying to control her, you explain that she is free to do whatever she wants, but so are you, and unless she wants to act like a married person, and live like one, you will let her be single. Her choice, she has complete freedom.
What will hurt your sons is not the truth, it is what she is doing. It is her actions that will hurt them, and her actions will destroy your family if you don't find a way to help her.
Here are some more links about plan A.
Mthrrhbard on Plan A and natural consequences I suggest that if she wants to have the freedom to do whatever she wants, then she also suffer the consenquences of her choices. Trying to shield her from them will only bring further harm.
Now, you don't know what will happen, but you need to take the path that has the MOST CHANCE of producing the best results.
Now about trust.
You shouldn't trust her until she is willing to account for all her time, until she can come and go acording to schedule, and until she gives you all computer passwords, phone records, and until her life is an open book to you. NO one has the right to destroy you in secret. IF she wants a private life, she has the right to get a D, and have it. YOu can't stop her, but you don't have to live with her if she isn't willing to act like a married person.
Remind her that she is free, but so are you.
Please tell us what your plan is, and if you have a hard time with making one, please call the Harleys (this site) for help. I think with the right plan, you have a good chance.
