Deciding Not to Join Family Trip Due to Surprise Inclusion of Sisters Boyfriend: AITA?

A 28-year-old woman agreed to join a long-planned family trip because her mom and sister kept insisting she’d make everything better, safer, and more fun. It sounded like one of those “just come, it’ll be great” deals, the kind you say yes to when you’re tired of hearing about it.

But the minute she bought the ticket, her sister casually dropped the real twist: her boyfriend was going too, and the sister was planning to extend her trip a few extra days without OP and without their mom. OP says the whole point of her agreeing was to be there for the family, not to bankroll a surprise couple extension.

Now OP is debating whether canceling would make her the villain, especially with the boyfriend showing up on the last day anyway.

Original Post

Long story short, my mom and sister have been planning a trip for a while, and they've been begging me to go, saying they’d have more fun with me there and would feel safer having me along. I've said no multiple times because I really didn’t want to go, but when my sister asked one last time, I finally agreed and bought my ticket.

Right after that, she mentioned that her boyfriend is also going and that she’s planning to extend her trip a few more days without me and my mom. The whole reason I agreed to go was to watch over them and enjoy a family trip together.

If I had known her boyfriend was going, I wouldn’t have agreed. Now I feel like she played me, and I’m really annoyed.

Would I be the a*****e if I canceled? Edit: Boyfriend will be showing up on our last day to stay with my sister a couple more days, this was the plan all along.

Will be going on trip

This gets messy like the friend who spiraled after being given unsolicited parenting advice, when your intentions do not match the impact.

The second OP agreed to go, the boyfriend news hit, and it instantly changed what the trip was “supposed” to be for OP and her mom.

Her sister’s plan to extend the trip without OP and their mom turns the original “we’ll be safer and have more fun” pitch into something else entirely.

OP’s frustration is basically, “If I knew the boyfriend was in the picture from the start, I would’ve stuck with my original no.”

Even with the edit that the boyfriend was always meant to join on the last day, OP is still stuck wondering if she was played into going at all.

OP might not be the a-hole for canceling, but her sister definitely made it feel like the ticket was the fine print.
