Reproducing With Exactly The Wrong Guy
A woman makes babies with a man she married to save from drinking and destructive behavior, and as a form of personal rebellion. An excerpt from the Advice Goddess column I just posted:

Sorry, but who "rebels" by becoming a suburban housewife? What are you, from a long line of pimps, prostitutes, and smack-addicted death metal artists?

At least you're clear on the fact that you married a man whose interest in children is akin to that of a guy I saw in Starbucks last month: intently reading the paper as his toddler ran around the place trying to pull a large iron sign over on himself, then seeing if he could crack his head open on any sharp objects. Yes, there's hands-on parenting, hands-off parenting, and "Hey, wait -- is that thing mine?"
