So my FH and I were discussing guest list. I would like to invite my best friend, who is gay, who happened to be a boyfriend for about a month quite a few years ago. He is in a committed relationship and has been with his partner for over 2 years now. We all hang out frequently and I know my FH isn't a fan of my friend's boyfriend, but he seems to get a long with my friend. He is inviting at least one ex-girlfriend that I am aware of. I have no issues with this since I know that this was YEARS ago and they have remained friends (similar to me and my friend) but he has issues with my friend and his boyfriend being invited.
He's pretty much flat out told me I can't invite them, which I think is a load of crap since this guy is my best friend. He is inviting at least one ex-girlfriend and I don't have a problem with it, and I'm just not sure what to do.
Help!
