For context, I (17F) live with my grandparents and recently my aunt and her son (13M) came to visit us a few weeks ago(he's home schooled and doesn't follow the same break pattern I do). During their five day visit I was in school for three of them.

Keep in mind i don't particularly get along with my younger cousin. He's a spoiled kid and his mom let's him do whatever he wants and it doesn't help that he cries when he doesn't get his way. Because I (thankfully) wasn't able to spend time with him during their visit he suggested that I come to Ohio with them for a few weeks for some 'quality cousin time'. I immediately said no because I have APs coming up and need to study and I knew I wouldn't be able to if I was missing three entire weeks of school. Besides, as aforementioned, I don't like the kid. I've spent time at their house before and watched his behavior first hand. He sprayed clorox in my face when I didn't wake up early enough and all his mom gave him was a slap on the wrist. He repeatedly beat, kicked and cried whenever I wouldn't let him touch my stuff and all his mother did was tell me to share MY things with him.

When I told my aunt no she kind of looked at me funny and I assumed we were done with it. I was wrong. The day they left as I was coming home from school they were in the driveway packing up their stuff with more suitcases than I remember them coming with. When I asked her about it she said she thought it over and decided that she wanted me to come stay with them for a few weeks. I again, told her no and went to grab a suitcase out of her car but she slapped my hand and told me to 'suck it up because my grandma had already agreed' which made zero sense because earlier she'd agreed that I couldn't go with them even if I wanted too.

After a while I started yelling, it was hot, my book bag was digging into my shoulders and I was still in uniform. My grandma came out to see what the fuss was about and I told her what was going on. She started yelling at my aunt and made her personally take everything out and back up to my room. When they left I'd realized my switch was missing and by the time they'd gotten home my cousin sent me a photo of my switch in his hands. I didn't get the chance to call him because my grandma had already seen it and called my aunt. I'm not sure what happened there or if I'm getting my switch back.

The problem really started though last week on my birthday. Since Covid we started a tradition of doing birthday zoom calls for the whole family, I spent the day with a bunch of my friends and later we started the call. Usually there are 10-25 of us on one call but literally no one came. Not one person in our family group chat responded to my grandma's zoom link. It was embarrassing to be stood up by my own family in front of my friends and I later found out my aunt had been telling everyone I 'insulted her and her son' and thus told everyone to boycott my birthday celebration. My mother was the only one with an excuse because she was working a double and told us before hand she couldn't make it and hadn’t heard about what happened, but everyone else thinks I was rude and should've just gone with them because my cousin has ADHD (most of us do so I'm not sure how that's relevant) to avoid hurting his feelings.

So, AITAH for not wanting to go stay with my cousin for a few weeks? I didn't think I was at first but seeing how quickly everyone got mad at me has me rethinking everything.
