A few years after high school I moved into a house and my best friend that Ive known for years happen to move next door. I happen to be married but I have a problem. I cheat on my wife with my ex that wont seem to go away. but what bothers me most is my best friends fiance and i have gotten close over the past few months and now hold a steady intimate relationship. I have a son and i do love my wife. however i dont want to lose my best friend. God I need a psychiatrist. What should I do... besides stop cheating (the obvious). I need to find out why i cant help myself.
