should I be this upset?? please help me figure this out

Kristen
I'm not a girl who has many friends. I moved around a lot growing up and at some point I stopped trying to get close to people.. But when I got to highschool I met a girl and we became closer than sisters. We have been friends now for 6 years. I'll make this short but I need help to know if I'm taking this too personal... When Lilly (this is what I'll call her) started dating Billy(another fake name) I was the one who would third wheel and I'm the one she confided in about their whole relationship. I always considered both of them good friends. Lily and I even got matching tattoos when I was living with her after I got kicked out of my house at 18... We would spend hours watching say yes to the dress and talking about our weddings. We always said we would be each others maids of honor.. Anyway I moved away a couple months ago and her and I don't hangout as often as we used to life has gotten busy for the both of us.. But she told me a couple days ago that I'm not even going to be in the wedding party because her fiancé doesn't like me...I've never given him a reason not to like me.. Other than dating guys he became friends with and when it didn't work out he has kept contact with two of them...but she vetoed one of his friends from the wedding party that she doesn't like so I'm the one he made her leave out... Should my bestfriend have fought harder for me? Should I care this much? I just feel like I don't belong at her wedding because obviously he doesn't want me to be a part of it..she said I'm still invited but how can I watch other girls be in her wedding party when we have been planning this for so long... All I know is if my fiancé didn't like her and didn't want her in the wedding I would say fuck you she's my bestfriend.. So maybe she just doesn't care like I thought she did... Thoughts? Would you be mad too?
