Fired as maid of honor..wtf? iin?

Lily and I have been best friends for 10 years. I am a mixed-race "American". Lily's parents immigrated from China. She was raised in a strict culture. It wasn't until college that she started embrace her individuality.

However, Lily got engaged last year to a caucasian-american man. Her parents initially attempted to disown her and caused a lot of stress in her life. Part of the way she handled her stress was by lashing out at me because I am american and "wouldn't understand filial piety". For the first time in our friendships, our racial and cultural issues became a bridge we couldn't span and a negative instead of a positive. It hurt to bear the brunt of her anger and be a punching bag but I understood the real cause of her stress. Perserverance finally earned her parents grudging acceptance.

I am Obsessed with weddings. I watch every bridal tv show there is, I finagle invites to weddings where i hardly know the couple. So Imagine my Joy when she asked me not only to be her MOH, but the only Bridesmaid. We went dress shopping with her mother. Her mother was very rude, loud, and insulted the quality of the dresses. The sales clerks kept giving me wide eyes and I was truly embarrassed. I kept my comments to praise or constructive criticism to help in finding a better dress style. Lily's mother later complained that I was too outspoken and negative and that I don't know my "place". Later, I was fired as a Maid of Honor. Lily told me that it had nothing to do with the fact that her mother doesn't like that i'm not asian. But I was replaced by her only Asian friend.

After that fight, we attempted to simply stop being friends. The amount of hurt and anger and betrayal felt worse than a divorce. What's worse, we are in the same friends circle and thus we kept having to attend the same events. We were even seated next to each other at a friend's wedding. It was so awkward that our friends begged us to fix it. We've tried to repair the friendship but everytime I have to hear about her wedding plans it's salt in the wound. And like a typical Bride, that's of course the only thing she can talk about.

Now, her new maid of honor has planned the Bachelorette party for a weekend that I cannot attend. Lily doesn't get married until December. I gently suggested that perhaps they could change the date and was told "Too Bad".

At this point, even if we make up later, I'm scared it's too late. That this friendship has been damaged too much. The one thing I don't think I can forgive is not getting to be apart of the biggest day of her life. I don't want to see wedding photos for years to come where I'm not by her side smiling with her. Everyone I've talked to said the relationship is toxic and I should just move on. But I don't want to lose my best friend!

Has she crossed a line? (yes) or is she right and i'm being a Drama Queen? (No)
