My ex-fiance called me three times and left a message saying he wanted to talk...should i return the call?

Wow. This guy sound like a total jerk. If I were you, I would return the call and give him a piece of my mind. Or, just completely ignore the call. This guy's not worth it. Plus, if you have a nice boyfriend, you should stay with him if he makes you feel happy. But honestly just do what you think you should do!
