Considering that you are equally as responsible for creating a baby as she is, you should step up and do your part in raising that child, because that's what any good person would do. I know it seems scary right now and it's a huge responsibility to take on, but that kid will also make you the happiest person and the love you'll feel for that child will be incomparable to any other thing you could possibly love. It's going to be a lot of work, but having a baby is also not the end of the world. You can still do everything you want to do like work, go to school, play sports, and go out with friends, it's just going to be a bit different. You'll be okay, I know plenty of teen couples who had a baby and they're just fine.
If not, congratulations, you're an idiot. You've made a mistake and now you need to take responsability for yourself. BE A DECENT HUMAIN BEING AND DON'T LEAVE HER. Stop asking people on the internet for help and tell your parents. They will be really angry but tell em. Talk to her. If she decides to keep the baby, you're gonna have to be responsible and support her and the child. You guys are really young and it sucks.
How do you leave someone you're not with? And you best be stepping up to be a father to the child you helped make.
You need to support her. Don't freak out dude, you must have thought of being a father someday. So, now is the time... i guess. She called you today right? First of all, just hope that she was fooling you. 😂 Meet her and if she really is pregnant, then congrats!! you're gonna be a father. :P
