Input: For  a little bit of background, I'm 15, my half-brother is 10. My parents  split up when I was a year old. I live with my dad throughout the week  and stay at my mom's on weekends. About a year or two after that she  married my step father (kind of a douchebag but I guess it could be  worse). Anyways, my half brother was born when I was 5 and we've been  getting along okay for the most part except for when we fight.

Yesterday, we were playing Mario Kart on the Switch that *I*  got for Christmas from my dad. I was beating him every round we played  and I could tell he was getting angry so I told him that we should take a  little break now. Really I just didn't want him to start screaming and  crying because I knew that I'd be getting yelled at before anyone even  asked what happened. I told him to just relax, we'd play later. He gave  in but not without ranting to his dad who said that I was mean to just  stop when \[brother\] had so much fun. Well, I don't know about you guys  but a 10 year old dark red in his face being so upset he was shaking  does not look to me like someone having fun.

I was pissed but okay, I went into my room to relax a bit. Some time later in the day my brother came into my  room, took "his" controller (the one I usually lend him) and asked if we  could play again. I told him that I didn't feel like playing Mario Kart  anymore today. He was getting upset and kept begging. I didn't give in  so he demanded I give him my Switch so he could practice. Once he  realized that that wasn't gonna happen either, he tried to grab my  Switch. I got it first and put it somewhere out of his reach. He got  furious and slammed the controller he was holding on the ground, then  ran out of my room crying and screaming how much of a jerk I was. Well.  Turns out he pretty much destroyed the controller now, I checked. There seems to be some kind of malfunction, you can't play with  it properly anymore.

A few moments after that, my mom came into my room yelling at me how horrible I was yadda yadda.

Now I'm fairly positive I wasn't an asshole in this situation.

What  I do wanna know is, AITA for not wanting to play with my brother at all  anymore? Shit like this happens every single weekend and I'm sick of it. I  pretty much only get in trouble with them when it's about  their "golden boy" (which in turn makes me the rotten boy or  what?). I know this isn't really his fault, he's just a kid with  anger issues but still I can't stand it anymore. I'm sick of spending  my weekends stressing about doing something small to set off my brother  and then getting yelled at. I know at first I will get into trouble for  making him cry because I won't play with him but in the long run I think  it will benefit me.
