Pretty easy one. Friend's having a birthday at a bar uptown. Invited me, his gf, and a few other mutual friends. He and his gf don't like my gf. Should I tell my gf the situation and go alone, or should I ask if she can come, or should I just show up with her? She wasnt invited.
Talk to him about it first and tell him that you want her to go. If you manage to convince him to let her go, then ask her if she wants to come. I'm assuming that you're smart enough to know what to say in both of these situations and that she's aware that they have some animosity towards her. I'm sure ethat they won't have a problem with her coming ad long as she doesn't start shit.
