Guy friends and boyfriends

Some of my good friends happen to be guys and my best friend is a guy and my boyfriend isn't to fond of it. He gets mad when I want to hang out with him and always thinks I'm cheating on him or I'm gonna leave him for said friend. I feel he's very jealous of the relationship I have with my best friend. He gets mad even when we're talking. It's so frustrating and it's gotten to the point where I feel like I need to lie when I hang out with him. Anyone else have this problem?
