Dude, why the fuck do you want a girlfriend? Both of you are way to young to be comitted to each other. Have a good time and play the field, stop trying to make every girl you meet your girlfriend! One day you will have a pemanent girlfriend and she will be called your wife, and then you are going to wish that you were 18 again. No one under the age of 25, especially guys have any business having a girlfriend, to much bullshit. Be free and fuck anything you can while your young
Also be careful because if you get her pregnant she just might want to keep that one to trap you, bitches are evil and work in mysterious ways, do you really wanna pay child support for 18 years and deal with the bitch for that long also? I'm just giving you something to think about. Apparently this chick didn't think birth control was a big deal last time when she got pregnant, who's to say she wouldn't think the same with you
