I know absolutely zero things about him other than that seems to feel entitled to respect he doesn't bother to offer to anyone else, and that he called you a bitch. I don't especially care to learn anything else.
And it'll blow over. Which I guess sounds insensitive, and I'm usually better at not sounding insensitive, but I'm tired, and I'm crabby, so I apologize if I'm coming off curt. It's shitty if his feelings were hurt, but he's got a friend group here, and I'm sure they'll want to do something for him, too. It's a tiny social gaffe. No one's going to hold it against you long-term. Promise.
