You're excused. Also the get educated is for many who think you can not get pregnant from the precum. As mentioned by another poster on here if semen is in the tube the precum can send it into the vagina potentially causing pregnancy.
Its funny how she is a "fucking bitch" now, but you fucked her before. You need to man up and talk to her. Yes she should show you the pregnancy test, in person. And yes you should get a paternity test, but there is NO reason to be a dick to her. You did what you did and ultimately it is her choice. Yeah its both of yours but she will be carrying around the kid for 9 months inside of her, so she gets to choose. Sounds like neither are you are responsible enough yet to have a kid and well you know the options. But you do NOT try to force her or guilt her into a decision. Even though to you this baby might just be nothing, to her obviously its something or she wouldn't have even told you. When you make that decision I don't care WHAT you believe about abortion you are killing you own flesh and blood, and you know it. You know how hard that can be to live with? You carry that around for the rest of your life, and who knows when you will get that chance again, or if you. So you putting any extra pressure on her, just makes you a big pile of shit that should be aborted yourself. Its her decision, so sit there and shut up. Be ready to pay child support bro.
