bf is being a dick

My bf gets mad at me if I talk to someone he doesn't like. This someone used to be a close friend of mine. Her and I used to work together and even though she's done some questionable things towards me I still have random conversations with her over fb messenger. He got mad at me because I said how I talked to her and he told me to get rid of her and to stop communication with her. I've already gave up one friend who was becoming family because of him. I don't tell him who he can and can't talk to. Sorry ladies had to get this off my chest.
