I am involved with a man that I have some concerns about. He hangs up the phone if you say something he doesn’t like, he accuses me of being unfaithful, he gets angry at the drop of a hat. He called me a very offending name and hung up the phone on me, then calls me back and acts like nothing is wrong.Please tell me what makes a person this angry or Jeykl and Hyde like. Is there anything I can do to help this person?Thank you for your time.
