"They chose to have a child with a man they weren't willing to marry."

Did they? What if he's the one who didn't want to marry? What if the pregnancy wasn't planned (which is generally the man's fault- please see: https://humanparts.medium.com/men-cause-100-of-unwanted-pregnancies-eb0e8288a7e5)?

And I seriously doubt anyone wants you to be the "cleanup man" ;)
