We are simply human; we all lash out and criticize from time to time. But treating you repeatedly as an emotional punching bag is unacceptable.
To mock, snark, or degrade someone is to treat them with contempt.
When someone commits an error, they can either apologise and accept fault or defend themselves.
Does your girlfriend prefer neater surroundings than you do? She will be furious with you for not cleaning up more frequently.
Your girlfriend may end up using all of your willpower and mental energy .
