Whether or not he is an alcoholic, he treats you in an awful manner. It sounds to me like he just wants to be free to drink or lay on the couch and if you interfere, he doesn't like it. If you don't live with him, how do you know for sure he isn't drinking during the week? Again, all of that is beside the point as to how he treats you. Is he the kind of person you really want for a boyfriend? I think you deserve better.
