Sometimes I think the "suspecting / finding out" part is so emotional that it's easy to be sort of numb once it's all out there and known. PS - Lexapro will do that also. I'm sorry you're going through this. You seem to be handling it pretty well. I wonder though - you're W seems pretty sure that you're going to be there for her when she wants you and a stable family life. You said "she thinks there's a really good chance we will end up back together in a year or two." What's her reaction when she plans things and you aren't available? I could be wrong, but maybe a less certainly would be good for her.
