I have 2 close friends who don't get along at all...goes even further than just not getting along...they hate each other. My sister is my Matron of Honor and then I also plan to ask a male cousin...we've been close since we were kids and I've always felt like he was more of a brother than a cousin. I've grown apart from one of them...which has me feeling sick anyway...we used to talk on the phone frequently...she rarely takes my calls anymore and always cancels plans but yet says I'm too busy now since I'm engaged and have such a "big shot" job (her words...not mine and so not true). I know she isn't happy herself and hasnt' been for a while so I get why she is having trouble being happy for me. We've been through a lot and I care about her feelings...but I feel like we aren't even friends anymore. Whenever we do talk she just unloads about how unhappy she is and the only comments she ever makes about my relationship is that she can't believe I am so happy and ready to get married.
How do I deal with this? I'm 100% sure that if I pick the happy one to be in my wedding and not the one I've grown apart from that it will end our friendship forever which I"m not sure I'm prepared to do that. However, I don't want my shower, bach party, or wedding to be uncomfortable. It's really stressing me out and I've been waiting around not asking either because I just dont' want to deal with it yet. My fiance has 4 people he wants to ask and I have another girl I'd be happy to ask in her place (someone I've become friends with in the last year) but I know that will really hurt my high school BF as it would be obvious that I had a spot for her and didn't ask her...I don't know what to do.
