UPDATE START Just found out she had a miscarriage this morning. So thank goodness for that. Now off to the store to buy him a box of condoms.
UPDATE END

My younger brother in law just got a random girl pregnant.
A girl he does not want a future with at all. Him being an idiot for not using protection aside, this is a really bad situation for him.

He's asked her to get an abortion. She wants to keep the baby. She has since moved out of her dad's house and is squatting at his mom's house. She's 18, no job, no car. A huge mooch.

Does he have any leg to stand on in this situation? Or is he simply stuck with either making this work out with her or paying child support for the kid?
