worst fucking advice I have ever seen. Yes, if she is abusive and hits him every time over literally nothing at all. Actually, even then you shouldn't even think about resisting to your parents in a physical manner(unless self-defense over someone trying to kill u or something like that). OP if she is abusive, you need to contact someone.
But if not then u probably deserved it and need to have a bigger heart than this even if you didn't deserve it. I prolly got beaten up by my momma every day when I was 14, Hell, I still get my ass whopped sometimes even though I am much older now. I am sure she loves you, so please don't take this advice 🙏. You should know the boundary of someone being regularly abusive other than being mad sometimes. If it's the first one, you need some help gl.
