Do you know what your partner is going to do or say from one moment to the next? Will he/she be loving and attentive one moment, the next raging and violent or withdrawn and uncommunicative? Should you try to change your partner? Do you need to change? Is there simply no hope at all? In The Dr. Jekyll/Mr. Hyde Syndrome: Couples in Chaos, Dr. Simon Casey describes what it means to either be or be involved with a person who experiences chaotic mood swings, and he offers specific steps to overcome the challenges such relationships present, including exercises designed to uncover just what specific "addiction" you may be dealing with.
