My boyfriend and I split 6 months ago. I have dated and hooked up with several men since, some of which I really liked. The problem is that whenever it ends with a newer one, I just go back to being sad about my ex-boyfriend. I always think I'm over him, until things fall with a newer guy. The weird thing is I don't think about any of the guys I thought I liked. It's like my ex is the only one with the power to truly hurt me.
