personally, I just walk away from that kind of crap (and similar stuff has happened to me) and eat the loss... I figure karma will eventually pop up...
Is it your job to "save" your W from herself? Maybe she'll learn or maybe she'll just try a different tactic next time to get money from you and your mom...
And you probably won't save her from jail time the next time she's busted for something much bigger... regardless of what you do, now... *shrug*
