I'm already married but in my culture, we do three events: the vows, the bride's reception and then the groom's reception. 

I live 5000miles away from my parents and got married here. My parents don't quite love my husband, they've only met him twice and the one time during our vows which they flew all the way over for my dad to give me away. 

My parents requests that I do at least the bride's reception as a way for my husband to meet the extended family and keep in line with tradition. I agree, so I flew back to my hometown alone in the summer and planned a wedding reception for early next year. I planned for a 100 guests, booked catering, booked entertainment, the whole thing and sent invites. It was supposed to be at my parent's home. 

I thought all is well, my husband and I will fly to my hometown and do the reception next year. Then two months ago my dad, who has never asked for anything from me and has given me everything, requests for an extra 50 seats for his guests. I agreed. 

A month ago, my mother found out about this request and went ape-shit. She's mad dad got more guests than she did! So she proceeded to invite 150 more guests of her own. Because of this, we aren't able to host the reception at our home anymore. Mother convinced me to book a wedding venue at 3x the initial cost. I then agreed, because hey, it's their day as much as mine. I transferred her all the money needed to book, changed the catering etc. 

Last week I found out my mother cancelled the entertainment I picked and hired street performers, the cost of the venue (which they expect me to pay) is $7k more than what they said it would, they invited people I loathe including my cousin WHO STOLE MONEY FROM US, picked a makeup artist that I did not agree to (too expensive!) and completely changed my menu. I no longer want to be apart of this. I will not show up out of principle. Invites are already sent, RSVP received. AITA?
