I really liked her letter Choco. Heck, I could have written some of that myself.
The key is to find a balance between her "space" and also working on reconnecting as H and W.
That is where my H and I are now and it really has been more effective than anything else we have tried. I can still have my friends, and career, and interests while building a better M with him.
It seems as though your W wants that too. The OM issue is definitely getting in the way of her reconnecting with you so I still think addressing that is a good thing.
Maybe she is fearful that she will not be able to maintain her newfound independence with you as her H. I think of that sometimes myself. It's like you get into this codependent R with your spouse and it's hard to see the two of you together any other way. But it can be done Choco. Keep trying. Don't give up.
