This might be fiction, but discussing about the moral dilemma is fun (for some of us at least) and make you think outside the box about/lets you see new sides to real life scenarios.
I don't get how people might think, that becoming father in your school time, does not screw up your future plans and will automatically lead to a life of happiness for everyone. (Sorry, if I got that wrong, but it sounded like that.) Founding a family does make the right people happy and they (I believe that's true for the majority of men) wish for one, one day. That is, when you are an established 25+ years old guy. Teen parenthood is...possible, but in most cases not what everyone wishes for.
Above in SHORT: Teen parenthood does block out many options for your future.
Well, MC takes responsibility and that is very commendable. In my book he does everything right. But he is in no obligation to marry a woman, he never actually did want to have children with. Imagine a guy, who meets a fly girl at a party. They want to have fun and she's on the pill, except she isn't. STD aside, maybe she wants kids somehow, no matter the cost, or her ex did a number on her contraceptives to get back at her for leaving him. Our guy becomes father. Okay, he has to take responsibility, even if it's only by paying alimony. The courts will judge that way, where I live here and good! The children are innocent and our guy had fun. But you can't force him into a relationship with a girl, he doesn't really know. No matter if she is an innocent "victim" of the situation or the perpetrator. And if our guy is able to live his life free so far, so is the MC.
Above in SHORT: Courts can force child support, but not love or marriages, which is a good thing.
He is free to date anyone he wants and we all know he will choose the dragon milf anyway.
