I don't want to pay child support and I don't want to be with e mother. Is there anything I can do?

The whole question was supposed to be is it possible I could prove that the mother is unfit as a parent and file for full custody of the child and give the child up for adoption?

Sure, if the mother is really unfit, is she a danger to the child. Is the only reason you want to do this, is not to pay support ? Since it is going to be hard to prove her unfit,
So tell us more about how she is unfit?

No, both parents have to sign off for an adoption to take place. Proving a mother unfit is going to be very hard.

I wanted an abortion because I feel we are not ready for a child, she wants to keep it out of spite and just wants child support. I make 3x more money and have my own place and my life is more balanced then hers is. She stays at home still works but sleeps on a couch. Financially she can't afford a child. But I don't want to have to pay child support because I don't want a court deciding how much to give based on how much I make. I work hard for everything I have and own. And I don't want to lose it. I need any suggestions. Thanks

Being rude, yes, keep your pants on. And let me see you want to kill a child because you don't want to pay for support, she wants to raise her child. You have nothing to show her unfit except she does not have a lot of money. That won't be a problem, she will when you pay.
