My (25F) sister (26F) has always been the golden child. Our parents have always favored her and it drove me crazy growing up. Everything she did was perfect, and I was always in her shadow. Fast forward to today, she's getting married in a few weeks, and of course, it's this grand, expensive affair that my parents and I are paying for.

Here's the thing: my sister is a total bridezilla. She demanded that I, her own sister, lose 20 pounds to fit into the dress she picked for me. She gave me a list of demands, including quitting my job a month before the wedding to help her with preparations. I work in a law office and can't afford to take that much time off because we have a big court date coming up, but she wouldn't hear any of it.

To make things worse, she made fun of my boyfriend (27M) for not making enough money as a doctor and said he couldn't come to the wedding unless he got her an expensive gift. My boyfriend is in his last year of residency and is debt free, I'm super proud of him. My boyfriend and I have been dating for 4 years, and we don't have a lot of extra money for the things on her registry. Things including: A Hermes teapot worth almost $900 and a set of six Lobmeyr glasses that cost $1,125.

She and my parents also coerced me in to spending my savings, almost $20,000 from my high school job on her wedding, because it was a joint account with my parents and they said they would just take the money if I didn't pay for what my sister wanted. I paid the deposit on the venue, the deposit for the catering, half of the flowers, the DJ, the down payment for the band and I bought her wedding dress. I have less than $200 left in that account.

After one particularly nasty argument, over my sister wanting to change her wedding dress, worth 3k to one worth almost 8k, I reached my breaking point. I logged into her wedding planning account (I know her password because I had to log in to pay for the down payments and deposits) and canceled all the bookings – the venue, the caterer, the flowers, everything. I figured she needed a reality check and maybe this would make her see how awful she's been acting. I only canceled stuff I paid for.

Well, she found out a few days later when the venue called to confirm the cancellation. She exploded on me, called me every name in the book, and now my parents are furious too. They’re saying I ruined everything and that I need to fix it, but there's no way everything can be rebooked in time for the original date.

Honestly, I feel a bit guilty, but I also feel like she had it coming. My parents are saying I went too far and that I owe her a huge apology and should pay for the damages again, but I think they’re just as much to blame for spoiling her all these years. AITA?
