I seriously need help please.

dont be a fool strap your tool

 

In addition to echoing praise of birth control, let me add my opinion:

As a sex partner, you are responsible for half the cost of an abortion, no matter the paternity.

If she doesn't go that route, get a paternity test.
I don't care what you thought or planned, if they're your genes, it's your kid and the kid needs support from you, no matter how crazy etc. the mom is.
(Emphasize: the kid needs support, mom's actions (past, present or future) don't remove your obligation to your kid.)

P.S. I didn't say any of this was fair to you, the kid or the mom. If you want "fair", read fiction.
