You might not understand it yet, but your life is changing for the better. From a worthless NEET to a respectable family man - all because you cummed in a stubborn girl. As you can see ITT, many can only dream about such a twist of fate.
>I will probably end up tied to her if not for life for a long time, losing the best of my youth
Stop being an egoistic twat and man the fuck up. What would you do if this didn't happen and you were free to enjoy "the best of your youth"? Cumming in more girls? "Partying"? Playing videogames or football with your pals? Doing coke and dancing to 3AM to shitty reggae? That's not a life worth of living, that's squandering your youth on meaningless distractions. But now your life has a chance to get a meaning. Don't lose this chance like a shitty loser.
>because a man should not depend on anyone
What a load of horseshit. Don't refuse help because of your pride - take pride in repaying people who helped you. Own your debts and repay them - that's what men do. Besides, don't you depend on your parents now? What would you do if they throw you out?
>I still feel like a little kid
Flash news, bucko! Everyone feel the same way! Part of becoming an adult is realizing that you will always stay a teenager partially - and that everyone else around is the same way. Children believe that there's some finely defined line that separates "children" from "adults" and that "adults" are these big powerful beings that always know what's right. That's not true. Being an adult means being responsible for your actions and open to new experiences, because only with new experiences we can change ourselves to better and grow as a person. A real man is growing his entire life.
Here's a plan of actions for you:
1.) First of all, contact her and then her parents. Tell her and her parents that you are very sorry and that you running away was just a instinctive reaction from the shock. But you thought it out, talked with your parents and now ready to return in her life and be a good husband.
2.) Tell her you're going to help her through the pregnancy. And do it. Visit her in hospital etc. Pick up some books or at least read some online forums to better understand what's going on with her body and mind - women do get mood swings and sometimes even more serious issues (like manias, for example) during pregnancy and several days after the birth, because their bodies get hit with a lot of hormones. You should be ready for that and help her to go through these things. Discuss with her if she wants a natural birth or a cesarean section.
3.) Talk with her parents about that job. The specific details, what would be required of you. If it's something relatively complex, may be pick up some books on the subject. Assure them that you have the full intention to support her and the child while she finish her education - and after that as well, of course (albeit I wouldn't be surprised if in a few years your wife would be the breadwinner in your family).
4.) Discuss with her and her parents were your new family would live. Who would help with the baby? They require 24/7 care, so someone should always be awake and near.
5.) Man the fuck up and enjoy your new life instead of being scared of change.
This. If I was OP I'd marry her first and then impregnate her. I'd fuck her day and night, I'd make her scream my name, I'd choke her, spank her and twist her nipples, I'd make her wear silk stockings and lace masks, I wouldn't get off from her, knocking her up again and again until our house wouldn't be full of little brown ninos.
