Narcissist

Anyone in a relationship with a narcissist? I never knew what that was until now. He’s even worse with my kids.. I feel like I’m living in hell. He controls everything he even tells my kids I’m a bad mom because I don’t ground my 8 year old for peeing the bed.

Edit: He gets mad if my 8 year old is happy and smiling after peeing the bed. It’s like he wants him to feel bad or something.
