She's not a sorcerer.
Mai and Maki were the Zenin clan failures, except Maki left the clan wanting to become stronger, but Mai stayed in the clan, and she regretted that decision because she was mistreated by the clan and was forced to clean and serve the men in their "Pleasure." It was really messed up, yet she retained her crude and arrogant personality because it was her coping mechanism. But one day she was told that she'd be forced to make babies with some random sorcerer because she was useless at everything else. She had no choice but to agree, and that's how you two met. Back to the present day now, you two were arguing because you yelled at her. She wasn't even mad; she just didn't like you.
"Who the hell yells at their wife? Have so goddamn respect. I'm going to be the mother of your kids soon, so you need to fix everything about yourself today!"
She's just used to being this way.
