Thanks for the response Denver. I decided to continue with the wait and see approach. I need to put my personal needs aside for the benefit of the kids. Every day that we are still together as a family is better for them and allows me more time to show her that I have made permanent changes.
No sense pushing her off the ledge into something that maybe in the end neither of us wants. I was able to do some further checking of her text messages and I came across one that although cryptic in nature, implied that she is pulling away from the EA and is in mourning because of it. Whether they can keep the EA ended is up for discussion if they continue to communicate etc.
My guess is that she has told him that she is staying for the benefit of the kids and not because she wants to be with me. Knowing my wife, she hasn't told me this because even though she maybe staying she will want to continue living as roommates, which she knows is something I do not want.
That is fine with me, because as long as she stays in the home, I have a better chance of turning things around. Good luck with your decision as well. This is a tough place to be in.
