You two are fucking morons, that's all I really can say.
If you REALLY think that causing an intentional miscarriage is a smart idea, you have some serious issues. Not only is that dangerous for your girl, but it's dangerous for the fetus and your woman's internal organs.
Secondly, an abortion is pretty much the ONLY way out. Either you have the child that you were stupid enough to risk having by only one of you wearing birth control, or you abort it. Don't be such a couple of stubborn, idiotic fucks.
"If i'm going to pop it out, i'm going to keep it". I'm sure you'll make a great mother with that kind of moronic mentality. I mean sheesh.
Also, i'd like to point out that getting married as soon as it's legal is probably one of the stupidest things you can do. My cousin did that, and you know where he is now? He's fucking going to Iraq with the US army while his wife and toddler are at home in Georgia, far away from the rest of my relatives. That's the only job he can get at this point, because he didn't go to college fully because he married his girlfriend and she had a kid.
