I am close friends with several of the guys that I work with. We joke around, give each other a hard time, and jokingly insult each other constantly. I have never been offended by this or gotten my feelings hurt. Recently (the past two months) I started dating one of my friends from work. Everything seems to be going well so far. The problem is that now when my new boyfriend jokes with me like we always have, (teasing, play fighting, giving each other a hard time, pretending to be mad/lecturing) it hurts my feelings. I don't understand why all of a sudden I have become more sensitive about this as it did not bother me at all, and I always laughed and did the same thing back to him when we were only friends. I think that this is because I dated a guy in the past that didn't treat me very well. He would say critical things to me and then after the fact say "I'm just joking" or talk to me harshly and blame me for everything. How can I not let this affect my new relationship?
