I just wanted to say that I remember about 6 weeks after I ended our relationship I had a weekend where I didn't leave the sofa and cried a bit. H asked me what was wrong and I was like I'm upset, my marriage is over. At that point yes I was the one who ended it, but I was still very very upset. I didn't think we could work on it. I didn't think there was any hope.
Telling him to work on it for any sake isn't going to change how he feels. He may truly believe that there isn't a chance right now. But that doesn't mean he'll always feel that.
He only said to you ILYBNILWY less than 8 weeks ago. He may still be in the shock phase and is trying to process everything. When I was the WAW I was in shock that it was actually ending that I'd said it out loud. The realisation that my marriage was over. And I felt really guilty that I'd ended it. That maybe I'd given up. So I just kept looking at any of his behaviour to reassure me I'd made the right decision. Anything he did wrong was like validation for my decision. Then I was angry about things that I'd never mentioned before. It felt really theraputic to say and you never did this and I always hated this. Just to be able to say things I'd put up with before. Then I missed him, his company, his sense of humour. But when we got together old things that upset me were still there. (because he was hurting I think) Then he detached, GAL, and we began to have better conversations about our relationship. just thought my timeline might help!
