Untrustworthy roommate, stealing, lieing, dirty, visitors,etc?

she..a coke slut drunk drama quen, manipulator, "poor me" never has rent on time (aka irresponsible) and selfish to say the least. me..lazy but respectful, responsible, love the "party," but not everyday, tipical "aquairan," (aloof, friendly, distant, peverse, independent, and disconnected.) Its really hard to shorten this story, but here it goes..... I met her once while i was bartending and we clicked and exchange #'s in the 15 min we shared. keep in contact only through texing, which was only about 3 texs with in 4 mths. we finally met up at the same time boyfriend moved out, couldn't afford rent, and i was scared. PERFECT! spoke my expectations and reflection was the same. I moved her in, paid for movers, rearranged my apt, etc. 3 mths later, she washed dishes, cleaned, brought common goods (ie toilet paper) once. since, im missing stuff! she happen to find the same exact digital cam as mine that just so happens to vanish, pain pill leave in 10's, etc. WHAT DO I DO??
