What to do about a coworker?

My boyfriend seems to have an issue with a coworker that I used to somewhat talk to cause he was trying to help me leave my boyfriend because my boyfriend treats me like crap. Well my boyfriend hates the guy now but yet will talk to him if he talks to him and tells me that if I talk to him it’s over that I won’t disrespect him by talking to the guy and me and the guy only talked as friends. Now everything is becoming too much on me I’m so emotionally drained I don't know whether to change my schedule to where I no longer work with him or keep my schedule and still be friends with the guy regardless of my boyfriend I just feel it’s all so immature. Thoughts?
