How can he be like this to me? Why?
Because he's an alcoholic and what matters most to him is the booze, not you. I'm sorry it's painful to hear/read, but the fact of the matter is, your own words show that he has little regard for you. He treats you this way because so far, you have shown him that it's ok to do so, because you'll be there to pick him up when he falls down, lend him money when he needs it, etc etc.
I'm not sure if this is your first post here, but if it is, I think you'll find an awesome group of very supportive people. You can post thread after thread, and people will respond with love and support. There's also awesome literature in the Classic Reading sticky you might want to check out...
SR is honestly what has helped me realize that I am a raging enabling codependent, and that my soon-to-be-ex-husband is in fact a highly functioning alcoholic (AND a lying manipulating psychopath, but we won't go into that right now). Until I found this place, I was lost, severely unhappy and didn't think there was a way out.
I really hope others have more advice for you. All I can tell you is that you don't deserve this, that you didn't cause his drinking, can't change it and can't cure it. Only he can decide that.
