So chick started copping pleas when you asked for your money?
You know you ain't getting that money back, right?
Personally you gotta take the L on this one cuz there is nothing you can really do to get that money back without incriminating yourself or spending more money. Personally, since she sounds manipulative I'd be manipulative right back. Front like you got some new money, tell her to keep what she owes you (cuz you ain' getting back anyway) then front like you big willie and don't return her calls/text/etc. Then after a month or two she will be fiending for the dizzle if she thinks you got options
