So I have a FB group for my BMs to make communication with them as easy as possible. I sent out a message asking them if they could meet a few days after new years on the weekend to pick out their dresses (each girl is picking their own style at the store, just same color). I did this so girls w/ jobs would be off and BMs in school would be on Christmas break still. FSIL never responded but I saw her at dinner tonight and asked her about it. She makes this weird attitude-y face and says "oh...ya...well, I have to work". I then reminded her it was a Sat. and she said "oh really? well I won't be in town on New Year's"...uh, ok..well neither will most of the girls but they are coming the few days after to go shopping. She lives 2 hours away and most of my girls live 2-6 hours away so it's not a distance thing. She then just told me to put her in anything, to which I reminded her that every girl is picking her own. She then asked if she could just look online or something. This girl has been a bride, BM a mil times, and a MOH, so she knows the drill and has always been super BM! Why she seems so disinterested in her own lil bro's wedding is beyond me and honestly, I'm pretty hurt. She basically decided she wasn't coming before she even had a legit excuse not too. What gives?
