Do I have the right to be a bitch?

Honestly. I am a very nice person until you disrespect me. I have family members that provoke me which make me a huge bitch. For example, I went out of my way to be in traffic for 3 and a half hours since my brothers can is having issues and took him all over. On his way back to his house he said he’d pay for gas. Well I am on my period and don’t feel well and he tells me to get down and put it Bc he is “preparing me to be a good wife” this seriously pissed me off and I said mean things. He was being such an asshole to me and I just lashed out. I hate being someone who says mean things out of anger Bc it’s just so ugly. I can’t help but lash out on him when he makes that fucked up comments with me and means it. How do you handle a family member that’s a bully?
