Why the hell is this line still trotted out?
I've even seen it on here. Woman falls pregnant, boyfriend doesn't want it and wants an abortion. She doesn't. People advise her to keep the baby and let him go. Don't bother seeking child maintenance because he didn't want the baby in the first place.
No!! If he didn't want a baby he should take his own precautions to preventing pregnancy. You don't like condoms? You don't have sex!
