What if I tell my girlfriend that she can't come to my best friend's wedding at his request?
Why doesn't he want her to go?
She said that the bride is too fat. I think he found out.
If she wasn't invited she shouldn't go to it. It's okay to have some things that you both won't be invited to.
Fuck you! You don't understand that my girlfriend might be hurt by this.
That's right, and it will be an awkward conversation but you should at some point have this conversation regardless because sometimes your partner won't be invited to your friend's special events.
