Mmmmm actually the act of not getting that "piece of paper" says that you have no intention of staying in that "committed monogamous relationship" if you are actually in one in the first place.
If you are in a "committed monogamous relationship" and having a baby then you get that "piece of paper" so you can have this thing called a "family" which is a group of people tied by blood and/or legal bonds.
Family, while something that is out of fashion now days, is proven to be the best way to raise children.
That she does not care to give her child a family is sad. That either she or her ""committed monogamous relationship" other has no interest in making sure their relationship with the child is safely and legally provided for is to say the relationship is unimportant.
So your concern is that two loving parents, who both happen to be millionaires, won’t be able to provide for their “family” because they don’t have a marriage contract?
