Boyfriend doesn’t want me to see my guy friend that I’ve known for 25 years?

We’ve been together 8 months. Long distance. I haven’t hung out with this guy friend the whole time and even longer because well I don’t live there anymore and 2 I just haven’t felt like it.
Ran into him last week and he said he should catch up sometime. Mind you, we’ve never dated. I’ve never liked him. I’m pretty sure he’s into men (which is completely fine of course). He’s basically one of the girls with the way he talks and everything. He’s never had a girlfriend.
Well, when I talked to my boyfriend about it, he claims that I just want to be alone with other men. That he doesn’t care how long I’ve known them. And I’m trying to tell him that they should meet for his comfort. He refuses. He says that I can do what I want but he’ll decide what he does when that day comes. I don’t know what to do. I feel like I’m being controlled.
