This is more just an opportunity for me to vent..First here is a little background..FI's group of friends are very close and most of his friends go back to Jr.High School. He asked one of these friends (lets call him

to be a groomsman. We don't see B a lot, we will see him for a couple months and then disappears for awhile then is back in the picture. Awhile ago he had informed me that when me and my FI first started dating me he didn't like me me because I wasn't "crew" and was new to the group, but that once he got to know me he accepted me as part of the "crew". None the less they are great friends and we are happy to have him as a groomsman.
B however is dating a girl who is very hard to handle she lies all the time, is overbearing and inappropriate...for example she has a tattoo below the belt and at a friends wedding she thought it was a good idea to show it off to a complete stranger in the bathroom. Needless to say she is not someone I spend any siginifcant time with and isn't really someone I see as a friend.
My BM's decided to through me a bachelorette party and asked me a list of girls I would like to invite. One of my BM's brought up the fact that I had not included B's girlfriend....she felt that I should invite her because she thinks B will resent me for not inviting her and will stand up with my FI on the wedding day having a sour taste in his mouth (he is aware of how all the girls feel about his girlfriend and admitts that she is hard to handle). I am torn because for the bachelorette party we are going away for the weekend and I know a lot of the girls have already said that they do not want to spend the weekend with her, and I am worried about her trying to show off her tattoos to any of the more conservative friends I have who would be extremely offended. I also don't feel I should have to go ahead and invite someone I do not consider my friend to my bachelorette party. My BM's already went ahead and contact this girl for her contact info to send her an invite, so I guess no I just have to wait and hope that she isn't able to come...so I feel like I am kind of stuck.
What do you think?
