My Dad was like that, he's gotten much more mellow since then though. Especially since my son came along. He adores my son, and I know he'd lay his life on the line for him. He's the polar opposite with him vs. the way he was with my brother and I.
I caught the brunt of his verbal abusiveness mainly because I always stepped in if he was coming down on my little brother and made myself the target of his words.
My brother never seemed grateful for it, nor did he ever share the contempt for my father that I had at the time. That, for a very long while, caused me to resent my brother as well. It also caused me to question if I was wrong in thinking Dad shouldn't be like that....it made me think it might be normal, bthat all families are like that and just don't talk about it. Of course I know better now at the ripe old age of 30. My brother is one of the most well adjusted, well rounded, nicest individuals you'll ever meet. I hope I had something to do with that.
Only after moving out did I learn to let go of a lot of that inward hatred and resentment. Even that took time though, the damage was already done.
It got to a point where I realized I was old and competent enough to know better than to blame any of my lifes failings on the way he treated me. That was an easy trap to fall into though.
My confidence is very close now to where it should have been all along and I think he sees that and respects it. I know he's sorry for what he did, though he's from the generation that doesn't really apologize, confess wrong doing, or talk about feelings. I know from his actions and words here and there though. And again, especially from the way he treats my son.
From the day my son was born my father changed 100%, it was a huge shock to me because I feared he might treat him the same way we got treated.
I love my Dad, it took me a long time to, but I do. I'll never forget what I went through, but I will forgive it. Otherwise, having resentemnt still will only poison me, and more importantly my relationship with my son.
I have full custody of my son, and his mother calls once in awhile, but otherwise isn't in his life. So naturally there are times when we get on each others nerves and we try each others patience. He's 9 too, so he's starting to really form his own identity, which is hard for both of us.
As long as I can remember though I've never ended a phone call, or left him with my parents to go somewhere, or dropped him off at school, or tucked him in good night without saying I love you to him....not once.
It's something my Dad never did and I guess it's important to me to know that no matter what my son and I may go through I will always love him. He gripes about it once in awhile if his friends are around or something, but I laugh and tell him tough titties, I'll tell him that every day, until the day I die.
