Welcome!
It seems like there are a few directions you could go that people have mentioned -
* Try to think less about your dad and more about how you can be happy
* Try to accept him as is
* Move on and let him go
All of them are viable choices. I think, at base is the question of what you need for you.
My sister is a real pill (details unimportant) and UBER PISSED ME OFF at my wedding. I was SO infuriated I did not call her for years. (She is so self obsessed, she didn't notice)
That was what I needed at that time.
Later, I decided I was holding a grudge and it was only hurting me. I decided if we talked, I would not need to bring the past up and I would make sure I would have strong boundaries that she could not cross.
That has worked well since.
I did have A LOT of guilt around "temporarily excommuniating" her. I realized I had to let that go. My job is just to take care of me, not to live out an expected relationship to a family member.
It sounds like you are doing a good job of thinking about how you feel and what you need.
Stick around and welcome, again,
Peace
