One of my good friends from college recently (within the past year) started dating a girl who, as indicated in the title, is a total buzzkill. She is very anti-social, and sits in the corner on her phone, pouting and complaining she wants to go home whenever a group hangs out. This isn't an "everyone knows each other but her" scenario either--this is in any social setting and has happened 4 or 5 times--even with her own friends around! Sadly, my friend isn't himself around her, having to cater to her whining. Everyone in my friend group, including my FH, seriously dislikes her. My friend must like her a lot, because they're planning on moving in together soon. Do I have to invite her to the wedding? Most friends are getting a plus one if they're cohabiting or engaged.
TL;DR: No one (including me and my FH) likes my college friend's gf. They're moving in together. Do I have to invite her to my wedding along with him?
