Why do guys always come back? My ex and I broke up 3 years ago. A few weeks later he got a new girl. Same weight, hair color, facial structure as me. I even met her and we are exactly alike. He gave her my perfume, shampoo and clothes. Basically tried to turn her into me. Every so often hell dump her and try coming back to me. It never works, just annoying. I finally blocked him because I didn't want to deal with it anymore. Here we are, about a year since I blocked him, and he's made a new Facebook and keeps trying to friend request me. Why, though? Obviously, I'm over it not to mention, I've moved 400 miles away since then, which he knows. So why bother? And why can't he just leave me alone?
