My wife is 29 and her mother is bipolar schizophrenic. about two years ago my wife cheated on me after 6 years or so. We are still together but she is constantly masturbating. When I confront her she blows up into a tyrant. She seems to like me the most in the mornings. She is constantly having problems with people at work and while driving. She just seems hypersexual, but not with me. could she be falling into her mothers illness? Thank you.
