So I've been friends with one of my bridesmaids since 6th grade. I don't have many close female friends and so even though we aren't best friends I asked her to be in my wedding because I care about her a lot and we have a lot of fun together. It is now a month before my wedding and she recently just turned 21 and wile she invited me to her B-day dinner (along with her family, friends and co-workers) she didn't invite me to any of the following partying with her other friends (admittedly I'm not close with them but we have met and got along great and its her birthday not theirs anyways) which lasted all weekend long and I could have easily attended. I'm very hurt and I'm not sure how she could not predict that this would hurt me but since we have never been BFFs we have never gotten in a fight before so I'm not sure how to deal with this (I also hate confrontation and always avoid it at all costs). Of course she is free to invite whoever she likes to her parties but it was flaunted in my face that I wasn't invited and I find this to be really hard to just move on and forget about.
So lately we haven't talked. I get the impression that she hasn't even noticed this because she seems very busy with all the friends that she did invite to her parties but she just texted me to ask about the seating arrangements and I responded saying that since we are having a sweetheart table she can sit with her boyfriend. To this she said "Oh he's not coming, I'm having my female friend come with me instead." This is one of the friends she has been so busy having fun with wile excluding me and wile I have met this friend and she seems nice I have only spent time with her twice and she wasn't invited.
Should I just excuse all of this and let it go and just focus on the fact that I'm thrilled to be marrying my fiance? Should I say something about all of this to her? As a bridesmaid she of course has a plus one invite but I'm also wrestling with being green with envy over her choosing this friend so blatantly over me this summer and I'm hurt about her not seeming to care about any of it. I don't want this to blow up on my wedding day (I'm very good at hiding my emotions so I don't expect that it would but it could still be very distracting) and I just want to know that everyone standing at the alter with me actually cares about me and my happiness. Please help!
