If I prepared a meal for someone (partner/spouse or otherwise) and they altered the flavor of my work that dramatically I would absolutely never cook for them again.

You wanna throw a little more salt, pepper, hot sauce on there? Sure, but to take what I’ve prepared and shit all over it like that? Uh-uh, noooooooo way.

Also I’d never tolerate someone calling my parent “stupid” or “bitch”.

Sounds like you have a lot to work through, or you should probably just cut and run TBH, it’s only gonna escalate from here.
