Stop being unfaithful. Call AA. Look for a new boyfriend. Many people can have a little too much to drink at a party and it doesn't make them an alcoholic. However, it appears when you drink you can't control your behavior and I don't blame your boyfriend. When in doubt think of this one ... how would you have liked your boyfriend kissing another girl and using the good old excuse he was drinking? Doesn't compute. Sounds like this guy knows what he wants and has made up his mind. It's best to move on.
