I had a boyfriend, but for some reasons we broke up, after two days of breaking up he sent me a message telling me he will ruin my life and he hates me. I told my best friend about it and I asked her not to talk to him because he hurt me a lot!

Turned out that my best friend was talking to him after that message in one week :// and she was getting it out of her chest to him and telling him about her problems and blah blah blah . So I ended our relationship together because I didn't like what she did , besides she shouldn't talk to someone who hates me because we're best friends! Am I right or not ?
