Sounds like a difficult situation @namechanged77, can you imagine wanting to be with him in X number of years or think in that same number of years you could have all of this over? Would the DCs be better longer term? Hmm.
I do think people can change IF they really want to, so maybe if he's starting to realise he has caused some of this, then maybe he can change... So tough without a crystal ball, and I don't know about you, but with DCs and everything else, I really struggle to actually have time and space to think about things at all! 
I've had a week of not really seeing much of H because we've been on conflicting shifts. I've felt so much more relaxed. Then this morning we were both there, and every time I move, he's there like some puppy. Since our first 'it's over' conversation, he's gone from extremely remorseful to convincing himself he's an angel and I'm betraying our marriage vows (because, apparently it's not his fault he drank our marriage away because alcoholism is an illness, thus negating any personal responsibility
). He swings between this, and denial mode.
I need to move things on. This week has shown me how I live when he's around, anxious, on edge, short on patience etc, and how it can be when he isn't. I'm just not sure I'm strong enough to tell him to move out. I know he doesn't have to, even if I do, but something has to give. I think my only other option is to start divorce proceedings, but I'm not sure I'm brave enough for that either yet
