I don't know what to think about this. One of my BM has done a 180 from when I first started planning and now seems to want nothing, or very little, to do with the wedding. I've confirmed that she is trying to get to the dress shop to try on her dress and get alterations done, and that she has a few different plans to find a pair of navy shoes (as all the BMs agreed on when we picked our dresses.) I'm happy about that because as of two days ago, I was convinced she was going to drop out - getting her dress and any other wedding related things - just didn't seem to be anywhere on her radar.
Now this is the part where I don't know how to feel. She has not recieved a bachelorette invite. It was her thought that she was left off the guest list on purpose since she said she wouldn't be able to attend. I provided the guest list to the BM who sent the invitations and I was slightly offended that she would think that a) I wouldn't put her on the list or

the BM who sent out the invites purposefully did not invite her. I know plans change so of course I had one sent to her one and she should get it anyday now.
Along with that - first she said she couldn't come to the bachelorette party, then she said she could, then she said she can't again. Ok, fineI understand that. BUT now she's telling me she could switch her hours and come, but that she probably won't because she'd rather hang out just the two of us and take me lingerie shopping instead of coming to my bachelorette party and bringing lingerie as a gift (It's a bachelorette party/lingerie shower). I could care less whether she buys me lingerie or not. The part that upsets me is that she hasn't tried to get to know any of the other bridesmaids and now she'd rather do something one on one with me than come hang out with all my friends. She isn't a shy person. I know that she doesn't get along with one of the BMs (the girl who sent the invite - the three of us lived together in college and for some unknown reason this girl can't stand the other girl.)
I guess my question is, is it generous to offer to hang out with me one-to-one or is it selfish because it seems she's just trying to avoid the other BMs?
I should note that there has been some miscommunication with the planning of the bacholorette party and I truly belive that's why she's avoiding the party. She is a person that always closes herself off and puts up walls to avoid situtations.
Sorry that turned out to be so long!
