For girls: Would U date an Alcoholic ?(read info plz)

well , I guess I am falling for a guy who's an alcoholic .. he asked me out many times but I don't know if it's okay to date him specially that I hate being so much in drinking just like what he is right now .. and thinking about him as an alcoholic drives me crazy .. should I say yes and try to change him ? or I should say no because it's a hopeless case ?! .. HELP !
