AITA for refusing to change my relationship with my stepbrother and not giving him access to my house or gaming setup?
My parents divorced when I (20m) was 7. My mom remarried when I was 10 and her husband's son, my stepbrother, was 8. He and I got along badly from the start.
He didn't like that I could do stuff he couldn't, like walk to the store on my own because it was right down the block from mom's house or that I was allowed to go to friends houses after school when I was with my dad. He was jealous about the gaming setup I had at dad's house too but that was mom's fault he even knew about it. She tried to force my dad to invite him over sometimes so he could play with me and she and her husband could have a date night.
We fought a lot and in the run up to the wedding we argued about being called brothers and having to stand next to each other during the wedding and they tried to force us into poses for pre-wedding photos and we refused. He even bit me during the shoot and then I refused to take more photos with him. Our relationship got worse and he would annoy me complaining about s__t so I rubbed in all the things I had that he didn't or could do that he couldn't do.
My mom begged me at the time to please treat him like a little brother and just try to be nicer and let stuff go and she said it was important because we'd always be family even if we hated it. He tried to befriend me once when we were like 13 and 11 and he wanted access to the good stuff but I didn't buy it and he let out on himself because he mentioned being invited to my dad's house like 10 times while playing nice. My dad died when I was 16 and my stepbrother mocked me because he'd get to play that stuff now because of course dad's stuff would be going to mom and his dad's house.
Only my grandparents kept it...
