I feel the same way. For months I have been sitting back and being as strong as possible as I watch my wife make decisions based on her 'feelings' for the OM.
Then one night we were together with the kids, and she suggested getting them dinner, so we were driving past 'tgi fridays' and I suggested it. She said 'you don't want to go there'. Apparently the OM has a friend that works there, and its a big hang out place for him and his friends.
OK. this is where everything changed for me. It sounds stupid, but its the straw the broke the camels back. If my wife wants to date a guy that hangs out at a TGI Fridays, fine. I honestly hope she finds happiness, but i'm not going to sit around and hope for her to come back to me while she explores a relationship with another man (especially one that hangs out at tgifridays). All these WAWs feel like they have us to fall back on. I'm done, she made her decisions, I'm better than that.
I told her yesterday, that I understand that she is confused right now (based on her telling me that recently), but i can't do it anymore, her words and her actions are saying different things to me. I am tired of feeling like I did something wrong, when I haven't done anything wrong.(when she gets in a funk because she is 'stuck' in our relationship). I just want the best for the kids, and i need to move on. I told her I hope she finds happiness, and her and him end up happy together.
