I kind of see this one a bit differently. I think that he is just a normal guy who has a wife that is mean to him, treats him like trash and cheats on him, all of this going on for years, and all of this drives him to drinking. Everything he says after the first verse implies this is not the first time this has happened, he is used to her going out and cheating and he goes out drinking every time she does it. He knows when he gets home she won't be there, that she is going to lie about where she has been when she does come home. He knows he does not have the strength to change her or go on without her and the cycle just continues, just another night, just another bottle.
