I'm sorry things are so difficult right now hootowlhoot - I know for many of us when we feel there's nothing else we cam do about a situation, we want to drink but that will just make things worse.
maybe some marriage counselling could help? I know your husband been resistant to that in the past - but to be honest I'm not sure I'd be pushing ahead with a house purchase right now with someone you've written about several times now who's shown little regard for your feelings and blames you for a lot of things where it takes two to tango.
Is there some other way you can you find a way to talk to your husband about the pressure you're under without appearing to apportion blame?
If you stay sober there's always a chance for change ...I don't think there's much of a chance if you drink again
almost any other option will beat running away into a bottle.
