Dude if she is pregnant and you are the father. That is your child no matter what, don't take out your hate on the child, it didn't ask to be born. You helped make it, do it some justice and be a dad. Be A Father Man!!!! Throw away your pride and ego an grow up and show some respossiblity.
You know if you just let go of the child, she will raise it to be just like her, and that child will be your child no matter if you are in its life or not. Do you want your child to grow up and be just like her???
I doubt it.
Just think about it, please.
