Ex's are trouble. Period. They have no place in a relationship unless it is as a co-parenting situation. The past is the past ... and it needs to stay there.

Once my wife and I got married her ex's started crawling out of the woodwork. At one point I explained that the next one that knocked on our door would be buried in the front yard. Then along came Facebook and here they came again.

My advice? Dump her. You don't deserve to have to deal with her old boyfriends in any fashion.
