I am looking for my father as well.
It was not that he did not want to be there.
My mom split from him and he didn't have much say in the matter because they weren't married yet.
He was in my life until I was almost 6.

First, it's not a good idea to piggy back your question on someone else's. I have moved your post to its own question.

Second--were you adopted? Did you have a step parent adopt you?

Third--how old are you?

Do you have any idea where he might be?? Ask your mom to help you find him!
