Don't ask negative questions please. He'll just cut you off again.
And then you'll never have answers.
I'm sure you're very angry, hurt and confused. He may well be a coward and he probably is. They just keep running.
If you want contact it may be on his terms. I have an absent Dad. He will never, ever be the father I wanted.
We have some 'relationship' but it's on his terms, which is always at arms length.
Don't expect much. Please don't. It will break your heart.
Instead work on yourself and forgiving him. This is the hardest thing to do. In some ways you go through a process of grief.
The last part is acceptance. You will never ever have what you wanted. But it's not your fault. There is nothing wrong with you. You are loved and lovable. Your parents are not perfect beings and nor should you ever expect them to be. For whatever reason he did what he did and he thought it was for the best - for him.
You can't hold onto rage where your parents are concerned. It just destroys you, leaves you in victimhood and depowers you to ever live the life you ever wanted.
Don't let your crap Dad disallow you to live the life you always wanted.
