Maybe I legitimately am in the wrong here?

So my mom's a narc and she's made an improvement lately (last 5 months or so), though she still shows some narcissistic manners. I can't forgive nor forget the 16+ years of shit I've been through before that, regardless of the improvement. She has mentally abused me for all my life.

I live with my parenrs and I feel like once I move out of their house there's no reason for me to keep in contact with her. Except for money and things like that. My dad's all good and I know they both would be willing to help me out financially.

I feel like I'd be a bad person if I kept in contact just for the money? Cause honestly I don't care about my mom. I don't wanna chat with her, spend time together or anything like that. If I'm being honest, I only care about her when I need or want something. I consciously act so that it's not that noticeable cause she obviously wouldn't like it. I do feel guilty for all of it but sometimes I feel like I shouldn't.

What do ya'll think?
