I haven't spoken to my father in over 20 years. Just not a good person. Don't miss him whatsoever. Glad I have a good mom at least.
It is not worth the effort to deal with harmful people. They will never give you any explanation for why they hurt you. Trying to get a meaningful apology is a complete waste of time and will only hurt you more. Some people are just narcissists and psychopaths. It is best to avoid from them 100%.
