Is frequently getting told shut up by your partner very disrespectful?

Someone I know confided about this. She feels unheard and unloved everything there is a difference in opinion on something or whenever there is a topic she doesn't agree, he always says ''shut up''. It's always a ''shut up or shhhh'' for everything that she doesn't agree on.

Personally I wouldn't tolerate being disrespected in that manner.
