I think my picker is broken, Despicable roommates and another sleigh ride to hell

Well, the Ex-roommate/GF has left the building. It only cost my friends (who collected for me) about $400.00 and an entire day wasted while the gal made changes to an agreement that stated that "She was being paid money to vacate the premises and not return". She added all sorts of clauses about not trying to collect money for past debt, not coming after for software purchased on my credit card for her laptop (wtf?), and wanted yet more clauses to hold her harmless for stealing items from me... huh? Now I have to wonder WHAT she took.... inventory after she left doesn't tell me much except that she is a pig; and you don't want to know the details.

I'm just a livid an-gry person who wants to hunt her down and after that... I"m not sure but I know it's not legal in the US.
