Your talk with your friend, I remember those. Seems like everyone wants to suddenly share their true opinion of your M and your S when they think it is over.
While sometimes I was truly amazed at things I heard, other times, I felt more like you do...
Yes what your W is doing is the pits and unfair and all of that stuff...
Not even here will you hear that it isn't.
It doesn't mean that you can't still try to make the marriage work. It doesn't mean that you can't someday (if you both choose) rebuild. Forgivness is a wonderful gift that we give to ourselves and other people.
Try not to let that conversation raise your anger. That could lead to emotional decisions that you could possibly regret down the road.
And listen, if there is something you want to do, then do it...
Your W, can always join you later down the road.
"Acceptance doesn't mean resignation. It means understanding that something is what it is and there's got to be a way through it."--Michael J. Fox
