Boreas is on point with her response. Relationships change, not always for the good. I am in a relationship with a heavy drinker as well, and he is NOT supportive of my attempts to stop drinking. We don't live together 24/7 as he has his place and I have mine (we live three hours driving distance from each other), and that's just fine with me. I need my alone time to recharge as well, he doesn't seem to require it although he maintains some golfing buddies so that works too.
Congrats on your 100 days! Awesome! I think relationships don't have to be "all in" to work. I hope for your sake you risk nothing more financially, that you preserve your savings and retirement accounts. My advice is to keep your finances separate. Good for you for staying strong!
