I agree with what everyone else said. It’s a form of bullying. They think that they can get away with disrespecting you for whatever reason. Can you please provide examples?

Do you speak up & tell them to not talk to you disrespectfully when they get mad at you? If not, then that’s probably one of the reasons why they blow up & you & not at other people.

Or there could be an imbalance in your relationship like they’re your boss & you’re an employee. They could just be a nasty sadistic abusive a**hole too.
