Double standards anyone?

So I dated a girl for a few months, it was shaping up to be a longterm thing, but things went bad. We basically went a few months with no contact, until she contacted me, saying she was a few months pregnant and needed my support. I was floored. We'd barely spoken since the breakup, and I was clear as day about the fact that I NEVER wanted kids.

This was one of the worst things that could conceivably happen to me. She suggested getting back together, which I shut down right out of the gate. I explained that we were through months ago, and that I don't want to be a father, and hung up. She is dead set on keeping it, there have been tests, and the kid is mine, though I dont know how the fuck it happened, since we were fairly strict with contraceptives.

I have a new GF, and we've just moved to a great new apartment. This phonecall literally shook me to my core, and I am freaking out like crazy. I've been searching for every possible way out, and I heard of a financial abortion, or whatever its called. Basically I want to resign any rights and responsibilities for the kid, since I never wanted him/her to begin with. I refuse to pay out the ass for a kid I don't want, and I obviously won't and can't force the mother to get rid of the baby, or give it up for adoption.

Her friends have called me, saying that I really hurt her by refusing to acknowledge this kid, and calling me selfish and whatnot, but I can't handle all that stuff right now, or ever probably. Am I the asshole for wanting a "financial abortion", that is, no contact, no child support, no custody, and is it morally and legally okay???
