““Extreme jealousy and extreme possessiveness always spell danger. If you are subjected to constant accusations, constant watching, spying, interrogation, or overreactions to such minor infractions as being late—be on your guard. If you talk to another man at a party and your partner overreacts with anger far out of proportion to the event, beware. This type of suspiciousness is a signal that the possibility of physical violence exists. Threats of violence, even if violence has not occurred before, should always be taken seriously. Plans for getting even, for revenge, and attempts to control you through threats of brute force are a clear sign that you need to have a backup plan for yourself.””
