My ex boyfriend that I broke up with has recently come out as gay and has a boyfriend, I have a very close guy friend that I have no feelings for but whenever I bring him up to my ex or he sees us together he gets mad and it is tearing our friendship apart, I'm just tired of him either hating me or wanting to be friends, I just don't get it he can have a boyfriend but I can't have a close guy friend what should I do?

It's time to tell him how you feel. If it was me I'd be direct;

"So, you don't want me, you're gay, you have a boyfriend, but...you don't want another guy to date me? You can't have both. You moved on, that's what I'm trying to do. You either support me, like a friend, or we stop being friends. The choice is yours".

Of course, that's me, I'm not known for being subtle. ;)

He's your EX Bf - right?

Well, stop talking to him about your friend, or stop seeing your Ex.

It's probably time to back off and cool the relationship with the ex. He sounds nasty and mean.

It is hard to stay friends with "ex's" that is why they are ex's.

I would be blunt and to the point and put the problem in his lap
