I refused to pay for my half of the vacation because my boyfriend secretly invited his mother for the last 3 days.

We agreed on a romantic 7-day getaway to Tulum. On day 4, his mother suddenly arrived at the resort because 'he felt bad she was lonely'. It ruined the absolute entire vibe. I packed my bags, went home early, and cancelled my half of the credit card split.

My mom's sister just passed away and she was devastated alone. It is a massive resort, I told my girlfriend she wouldn't even see my mom. Walking out, flying home, and leaving me with the hotel bill is incredibly selfish behavior.

No concrete evidence was submitted to the locker.

⚖️ Final AI Verdict from The Judgy

Based on the evidence and arguments, Side A (the boyfriend) made a significant unilateral change to a romantic couples' vacation without consent, which is an explicit violation of the trip's premise. Therefore, Side B (the girlfriend) is justified in leaving early and refusing to pay for a vacation that was fundamentally altered against her wishes.
