He broke up with you but that does not mean that he doesn't feel hurt. I broke up with a girlfriend 4 months ago because I knew she would never feel the same way about me that I feel about her and I want a girlfriend who really, really wants to be with me. I still feel some hurt about that relationship.
Maybe friends convinced him to break up with you, maybe it was his decision and he now thinks it was a mistake, or maybe he blames you for whatever reason he thought required the break up. Whatever the reason. . . he is trash talking you now as a means of punishing you and convincing himself that he was morally right for breaking up with you. (Maybe he cheated on you and is convincing himself that you "deserved" to be cheated on."
What do you want from him now? In your innermost heart. . . not worrying about what your family or friends would say about your decision. . . do you wish that you two were back together?

Bitterness. Often times boys (or girls) don't know how to interact with exes. So they unfortunately revert to their younger adolescent selves. I suggest you just take the high road and be cordial, polite and friend-ly.
I'm curious though, how did the break up occur if you had nothing to do with or?1
