why her?

Recently I have had this situation where one of my ex's is dating one of my now former friends. Am I jealous? Not sure. Out of all the girls you had to chose from you chose her. Like what. This is why I hate setting people up with cute double dates because some reason those two always end up getting together. It's okay I am over it it just bugs me. I can't help but not care because I was in your life first.
