If real, the only man who would agree is a man who is deep in a church community. At that point, the children are being raised by the church.
She doesn't seem like a religious fundamentalist so she's either going to have to jump into that community or wait until those children grow up.
How does she even have time to be attending these kinds of things. One child is hard enough to take care of, 6 on top of that should have your head on a swivel. Look away for one moment and somehow one of them is on a surface they can't get down from and screaming because they're scared.
Nobody put a gun to his head after the second child and said "now make 5 more" he chose to bust raw and she chose to let him. The only victims here are the children that didn't ask for such dumb ass people to raise them.
