I guess I just worry that this won't get you where you want to go. I know when I was a WAW if one of my family members even slightly said "is there no chance ?" I would get really angry and feel like everyone was piling up against me. It's not logical or rational. Just to say when you're in that frame of mind you're really determined.
I think it's great that you still have a relationship. I love my MIL so much and it's sad that we don't see as much of each other. But I also know that he'd just feel beaten into submission of his family said you really ought to give her another chance.
