The ideal of marriage requires that both parties adjust to each others' life. You cannot be an individual with your own life if your life is really someone else's. Marriage is an artifact of an age in which women were essentially slaves to their men. Perhaps well-treated, but still subservient. Granted that there were economic reasons to do so, but that doesn't change the end result.
Marriage remains an agreement to servitude.
You don't need a marriage license to do that. Be responsible and be prepared to share the responsibilities of child rearing. So don't make the same mistake again. Don't make a lesser mistake again. You get married, find you don't get on, and then you are either in a bad marriage or a good divorce.
