"Hurt people, hurt, people..."
If your father wasn't there for you, the fact is, you still made it. It may have been harder and you may have gone through a lot of things you don't think you should have gone through, but you have made it and are making it. Do _YOURSELF_ a big favor and forgive him.
I mean _REALLY_ For.Give.Him. Release the hurt and the anger that has manifested because of the hurt. Let it go, for yourself. It will do you and your spirit good.
"Easier said than done."
Yes, it is. But you have to do it.
Next, if you can, tell him you forgive him and then have let it go. Do it with no expectations of "I'm sorry" or anything. Just do it.
I've seen too much hurt today and it saddens me.
If you're in this situation and you're a man, just pledge to do better and do better.
