Invalidation is an aggressive form of emotional abuse. If someone uses invalidation on you it is important to recognize it and to understand that they are not looking for a compromise or a way to meet you in the middle at that particular moment. They are using a power play to win – to suppress your needs in favor of their own. Recognizing invalidation should be a cue to calmly reject the falsehood in the accusation and quickly exit the conversation.
When someone uses invalidation, you are temporarily released from any moral obligation to compromise or try to further resolve the problem. Instead, it is a time to focus your energy on protecting yourself, your children, your assets and your dignity. Compromises and resolution can be attempted later, if and when the other person decides to adopt a different approach and communicate with you in a respectful, validating manner.
The above was a copy and paste so I could comment below. Yes it is power and control as mentioned in the first paragraph.
Compromise is a dirty word, negotiate is better. Verbal judo and aikido will work as well. Compromise what? So they can do it again?
