I Need Advice

I'M Now In A Relationship With Someone Who Used To Be My Crush... So... I really need advice. People keep telling me he's not worth the effort. I know, he sure has his "details", but I'm not perfect either. He has this big problem and I think it will affect us somehow: he drinks a lot.

He told me he wants this relationship to work, but for starters, I want to have a conversation with him about our relationship when he's totally sober.

We used to be involved in some kind of relationship before, but at that time he didn't want to be my boyfriend and now he says he wants to do things right, but I think this habit of his will be really hard to overcome :/
