She should be kissing the guy’s feet. He saved her from marrying jailbait.
I’ve seen plenty of relationships where people have married such. Once in a blue moon the guy learns his lesson, gets out, and devotes himself to making sure his kids have a better life than he was headed on.
More often I’ve seen the woman end up years later with nothing and unimpressive, emotionally damaged children.
She apparently is not a saint herself and jail is apparently nothing new to her.
