I'd make a list of the things that you bring to the table and that he brings to the table. If he's an active alcoholic, he doesn't bring a whole lot. I'd suggest reading the sticky notes at the top of this forum so you understand what you're in for. Talk is cheap and manipulation runs freely. Do you want to knowingly take that on? What is it that draws you to him? It's well worth the exercise. It also only works if you are truly honest with yourself about why you have chosen him. Good luck!
