So, I met my buddy in a crisis residential unit and we became really good friends really fast. We both left the CRU together homeless and sober, he was a drinker and I was a weed smoker and took prescription meds. We decided to stick together and support each other. We were only homeless for a night before I moved in with my girlfriend and she was more than willing to take him in too.

He is a really good guy and very likeable but he has started drinking again. It started out with a couple beers here and there then gradually became a 6 pack a night. I work midnights so I leave him here with my girlfriend and her daughter which is no big deal as far as their safety, I trust him, and so does she, but last night he came home before I left for work and was the drunkest I've seen him yet. He said he was at the bar with a buddy from work.

My girlfriend puts up with it because she knows he's a really good friend of mine and she likes him as well but not his drinking. Last night he was smoking a cigarette and burnt her ottoman and she isn't happy at all.

How do I go about confronting him about his drinking and letting him know he can't be drinking here or coming home super drunk anymore without him feeling like we don't want him here or that we are against him because we're not and we don't want him to feel uncomfortable here or around us. Any advice is appreciated.
