Just a point about this whole situation: OP may not want to be a parent, but (if he is the true biodad) he already is a "father" by virtue of fathering this child. It is a bit like a woman conceiving, then saying that she doesn't want to have a baby. Well, she IS pregnant and does have a baby....just like he IS a father in the legal and biological sense. Today a woman has the legal ability to end the pregnancy by killing the baby, but it is STILL a baby no matter what you call it or do to it. In this case, OP is STILL the father no matter what else he or we call it. But, of course he can choose to not have contact with the child for the rest of his or the child's life. I wonder what that child will feel like someday, but heck.....it's just an inconvenience.
Hopefully, a good man will step up and be an example for him/her so he/she doesn't make the same mistake. A good dad is as important as a good mom. It's a shame too many boys and girls don't get the chance to see what a good dad is.
So the cycle continues......
