Guess it hit me harder than I thought. Didn't sleep at all last night. Thanks ballast and anotherstander for your words. I held it together last night and she seems really torn up and I am actively trying to avoid interacting with her. I've been letting her cake eat since this whole thing started and I realize now that it was a mistake. I'm so emotionally wrecked right now. She apologized via text this morning (not for having the EA, but about last night in general) and I decided not to respond. I think the worst part is that the OM is (was) a mutual friend and her coworker.
AnotherStander, I have zero expectations of my wife right now other than she keep her share of the house clean. I've backed off from romantic gestures completely. We had disagreements and I feel like they were resolved, but perhaps she just bottled up her resentment. I'm definitely a partial NG, not full blown NGS, but enough to make me address it. I'm reading the book now. Thanks for the GAL stuff, I'm working on my own though building meaningful friendships was never my strong suite. Another thing I have to work on.
