Okay, I suck at social etiquette so I figure I better ask before I make an ass of myself...
I have a friend, A, who I met on the last movie. She developed a really deep thing for my friend J, who is one of my boyfriend's closest friends and a good friend of mine too. J has a girlfriend who he is very committed to, so he is avoiding A.
A and I made plans to go out tonight for New Year's at a place near my house. Then J called; he and his girl are back in town and want to hang. I told him that I was trying to get a group together for this place and he was interested, until I mentioned that A would be there, and he vaguely said maybe they would drop by.
I would really rather go out with J and his girlfriend, especially since A just left me a message saying she wants to go to another party over on her side of town. I don't want to drive across town on NYE with all the traffic and drunks on the road. And like I said, I'd rather hang with J. But I made plans with A first. What's the proper thing to do?
