If he says you've got it all wrong and dismisses what you're explaining and detailing to him, he is minimizing and dismissing the impact it's had on you, and he is not validating your experiences or your feelings. That would really bother me in a relationship, if it were me.

Can you talk to him about his responses to you, tell him what you need from him when you talk to him about these things, and tell him that you feel invalidated because he tells you you have it all wrong? You're not wrong. It's your experience. If you are being bullied, you are being bullied. And if you have a narc parent and toxic family, that is going to effect you negatively, and that's very valid. Sounds like he cannot be supportive of you, which is what you need from him. I would talk to him about this. You need support and validation. Hugs to you.
