The hard truth is, though, that it isn't his life that will be ruined. He will dictate the terms of his involvement with the child, and if he so chooses he can walk away with at most a financial cost. He won't be the one who is kicked out/faces pressure to drop out of school. He isn't the one who will have to quit extracurriculars or give up dreams of a traditional college experience. He isn't the one who will need babysitters to date or hang out with friends. He's not the one who will lose friends or have a hard time finding a suitable mate when he is ready to marry because of his "baggage". Not only does the entire physical toll of pregnancy and birth rest with the mother, the vast majority of the social and emotional toll does as well. It is only fitting that the mother should have the final word on whether or not to assume that responsibility.
If he is in on the front end of the decision though, the girl will KNOW what she is getting into with him. If he doesn't want to take responsibility then like, FireDancer says, he gives up his right to the child or the right to choose what happens as far as abortion or adoption. IMHO, we can't have it both ways. We can't say to these guys "its your responsibility to take care of this child by providing" but oh, by the way, you get no choice as to whether the pregnancy is aborted or the child is given up for adoption or she keeps the child. And so, we have so many that do walk away.
I know that all males are not going to step up and take care his child; but then neither are all females. He should at least be given the opportunity to do so.
My younger son was 25 before his first child came along, so not a teen-ager, but an unplanned pregnancy. And when she found out they were not even dating. Fortunately, she came to him and let him know that she was pregnant. THEY decided what would happen. At the time, they decided to keep the baby and they would raise it together but not as a couple. Things changed and they are married now, but because she came to him in the first place, he had the opportunity to let her know he would step up and take care of his child. I thank the heavens above that she gave him that choice.
You mention being pressured to drop out of school, only the parent can do that. The school system can NOT do that, its against the law. Nor can they make her give up extra curricular activities unless it is something that is dangerous for the baby. For a young man that does step up to take care of his child, then yes he will have to give up as much as she does for the child. Hard to play baseball, go to school and keep a job to pay for diapers, clothes, food, etc.
Many, many, many males will, in fact, have the same emotional baggage as the girl when it comes to the pregnancy being aborted or their child being given up for adoption.
I don't think we give enough credit to young men and their feelings toward their own child.
