Welcome FC!
I am a recovering alcoholic so I am really not the one that should be giving advice
but I will just say that if I were you, I would plan on going and I would tell the hubby that I would rather he NOT go because you would be more comfortable without him being there (possibly drinking and definitely stirring up bad feelings). But that is just me. You should not miss out on Christmas but if he refuses to deal with his problem, then I would refuse to deal with him under those circumstances. MOO
