ex problems

I broke up my my bf of two years about 3 months ago unexpectedly (he just needs to grow up and I was sick of taking care of a grown ass man without ever recieving the same treatment). We have a ton of mutual friends. Everytime I hang out with one of my friends they will tell me how he always says how heart broken he is and how he wants

me back into his life. Ill try to talk to him because I feel bad, and hell just be a dick or ignore me but will continue to go around saying things about me. My friend told me to stop feeling bad because hes just playing victim to get sympathy, but I cant help it. What do I do?
