How do I deal with a father I hate?

I’m asking more for religious/spiritual reasons. I don’t really want to go on about it because it pains me deeply, and I have serious feelings of emotional abandonment and abuse from my father. My mother and me both feel (sister as well, although she is completely no contact) that my father is a person with Narcissistic Personality Disorder.

Am I obligated in any way to have a relationship or take care of my father in old age? As in am I obligated via the Torah or Rabbinical interpretation?

For my mental health and sense of self I would rather never speak to him again. I feel pretty defeated right now and could use emotional support and guidance.
