AITA for cutting all contact with my family because of a prank?

So I have posted a story on here before and I got some pretty good advice so please help. Here’s what happened. I (27F) have always had a complicated relationship with my family. They’ve always been the type of people who think any joke is fine as long as someone laughs, no matter who gets hurt. Over the years, I’ve tried to brush it off and not let it bother me too much, but this time, they crossed a line I can’t ignore.

Recently, I achieved something big in my life: I bought my first home after saving for years. It’s something I worked incredibly hard for sacrificing vacations, nights out, and basically anything extra to make it happen. I was beyond proud of myself and excited to finally have a place to call my own. Naturally, I wanted to share this milestone with my family, even though our relationship has always been rocky.

A few weeks ago, we had a family dinner to celebrate my new home. Everything seemed fine at first, they congratulated me, asked about the house, and seemed genuinely happy for me. But halfway through the night, my brother (30M) and sister (25F) handed me an envelope. They said it was a "surprise" to help me with my house.

I opened it, and inside was what looked like a legal notice stating that my house purchase had been canceled because of a "clerical error" and that it was now being sold to someone else. It even had an official looking letterhead, my name, and details about the house. I was in complete shock.

Everyone around the table started laughing, and my brother yelled, “Gotcha!” Turns out, they had faked the letter and thought it would be hilarious to see my reaction. I burst into tears, which only made them laugh harder. They even recorded the whole thing on their phones to post on social media.

When I finally managed to speak, I told them how cruel this was. Buying this house was the biggest thing I’d ever done, and they turned it into a joke at my expense. Their response? “You’re so sensitive. It was just a prank. Lighten up!”

I left the dinner early, completely heartbroken. A few days later, I decided I’d had enough. This wasn’t the first time they’d pulled a “prank” like this. Over the years, they’ve humiliated me countless times once ruining a job interview outfit by “accidentally” spilling coffee on it, another time pretending to lose my dog just to see me panic.

I cut off all contact. I didn’t make a scene, I just stopped responding to messages, blocked them on social media, and declined invites to family events. Now, I’m getting guilt-tripping messages from extended family saying I’m being selfish and tearing the family apart. My mom even left me a voicemail crying about how much she misses me and begging me to come back.

But I can’t bring myself to forgive them. This prank felt like the final straw, and I don’t see how I can trust them again.

So, Reddit, AITA for cutting off my family over this prank?

Edit: Thank you all for the advice and support. I wanted to provide an update because things have escalated in ways I never expected.

After I went no-contact with my family, I thought they’d eventually accept my decision and move on, but that hasn’t been the case. For the past few weeks, my brother and sister have been trying to get me to “see the funny side” of their prank. They’ve shown up at my house uninvited multiple times, banging on the door and demanding to talk to me. At first, I ignored them, but it became clear they weren’t going to stop.

One evening, I caught them standing outside my house with their phones out, recording themselves while yelling things like, “She can’t take a joke!” and “Let’s see how long she can hide!” It felt more like harassment than an attempt to reconcile.

The final straw came when I discovered my car had been egged overnight, and my security camera caught my brother and sister doing it. I confronted them through text, telling them they’d crossed a line and needed to stop. Their response? “You’re so dramatic. You’re going to laugh about this one day.”

At this point, I realized I couldn’t handle this on my own. I went to the police and filed a report for harassment. They took my statement, reviewed the footage from my security camera, and agreed that this behavior was unacceptable. My siblings were contacted and warned to stay away from me.

Their reaction? More mocking messages, calling me a “snitch” and accusing me of tearing the family apart. Some of my extended family members are siding with them, saying I should’ve just talked it out instead of involving the police. But others, especially those who’ve seen the footage, are horrified and fully support my decision.

I feel a mix of relief and sadness. It’s hard to accept that my own family could treat me this way, but I also feel safer knowing I’ve taken steps to protect myself. I’m focusing on building a new life in my home and surrounding myself with people who respect and support me.

To anyone out there struggling with toxic family dynamics: You’re not alone, and it’s okay to set boundaries to protect your peace. Thank you for giving me the strength to stand up for myself. ❤️
