What Should I Do??? Everything Just Got Complicated!!!?

ok so i was talking to one of my friends a couple days ago and he asked if i had a problem with people that drink and i say yes. (ive lost my grandparents, and sum of my uncles and aunts to drinking) and i ask y. he refuses to answer. so finally last night, i get him to answer and he says that its my crush that drinks, we went out twice and were really starting to like each other. so now idk what to do!! i really really like my crush, but idk if i can be with sum1 that drinks. friend says that when crush drinks he doesnt know when to stop. so i ask does he drink often or just like every once in a while? he didnt give me a straight answer so i think it was often.

idk what to do!! i want to be with this guy so badly, but i dont know if i can deal with a drinker. friend says if i talk to crush he will stop, but im not sure i can even talk to him about this. i want to i really do but... idk i cant just walk up to him and tell him i know everything.

help!!!!
