Hmm, yeah, your life sucks. But you are the one who decided to marry her, so, if her character always was like this, than you also deserve it. If she has changed through time, well, maybe it's time to save your marriage. Go talk to your wife, there might be a reason why she is acting like a bitch. If comunicating doesn't work, you could think about a divorce. Things aren't going well if you call your own wife a bitch, even if she acts like one.
