You should've used condoms.
Unless you were married, then I don't feel too bad for you.
How is she lousy for getting child support?
Getting child support doesn't make her lousy. If he's not supporting his child, what can she do?
I don't know her side, all I know is his side and his side said he does support his kid.

If that's true, she's lousy for putting him on a system that doesn't give a fukk about him, her, or her kids. A system that will take every thing he'll need to provide a living for his kids for something as simple as paperwork not being filed correctly. Child support system is irrevocably broken and often misused to punish people for not wanting to continue a relationship.
Any woman who puts their man in that system because he's doing... but not doing
enough is fukking lousy.
