Hang in there. Just keep being a good dad.

What I wouldn't have given to have a safe space away from my narcissist father when I was 17 years old.

You can't break the cycle yourself, your daughter has to be the one to do it. I think it's much more likely that she can accomplish this with a healthy, unconditionally loving father in her corner.

I know it's hurtful to watch her be puppeted, emotional abused. I'm sure it hurts to have her brush you off for long periods because that's what her mother wants. But she's 17. She may need some time to step out from her mother's very large shadow.
