I'm the BW and I feel like I'm falling apart yet I'm supposed to just get on with it according to WH. WH talks about nothing but how depressed he is and expects support and sympathy. He has shown no remorse and I think he is just pining after ow. Obviously I have no idea what it feels like to be in his position but I suspect it's harder on the one who is betrayed.
You have an unremorseful WS - so, gently, very gently, - why are you staying with him, may I ask? It seems like he continues to hurt you, first with the A and now with his lack of caring over your feelings. If he is so careless with your feelings, both to have an A and now to not care that you're hurting, what is it that keeps him in your life?
