Unreality, it just spins

So talking with the one roommate over the phone early this evening as I was commuting back from a class elsewhere (about an hour commute); I get yet another sugar coated surprise.

First, she tells me that she had a really great time with her son whom she visited (which I think is great), then acknowledges that we need to talk and we agree on this weekend; because we have to be sober and because I'm booked until Friday afternoon when I proctor the class I'm auditing.

She tells me that she is going to sue our mutual "friend" for defamation of character which she characterizes as a felony; it isn't, as far as I can tell it's a civil matter unless some other rules which I have not researched apply. See link1. And civil matters have to show injury, and if you wish monetary compensation you have to show losses.  (Or did I get that wrong? I have to check)...

Great.  Now she is on tilt.

So the surprise...

She "reviewed" the amount of work that she has "done" for the house, and determined that I probably owe her money.  I am speechless.  Our agreement was she paid rent, and contributed about $150-200 a month in cleaning effort... and anything else she did was because she insisted.  (It helps her with stress to have projects to do, never mind whether I agreed to them or not)...
And I offered to drive her (the agreement was she'd cover gas) for 5 trips to south orange county and back that I can document.  So who's time is worth more?

I told her I would not kick her out over rent, but this is not what I agreed to...

She hasn't paid rent since 8 weeks ago as of now, owes just under $800 (8 weeks minus a little), and is disregarding the $330 in direct loan expenses (hair colour, vision checkup, cigarettes, her cellphone bill and she even talked me into buying her beverages..).

I'm not including the emergency room visit ($140), the followup doctor's visits  to inspect and later remove stitches,  or the damn wusthof solingen classic 8 inch kitchen knife  (about $159 discounted) that the local police department "lost".

I figure it almost $1400... if I count the incident... which is more than she's ever made doing her thing since I have known her.  And I'm not her boyfriend/toy or client...  (and all I really asked her for was the $300 -- because I figure she's good for about that much maybe).

And if I do anything at all, it will be "my fault".

splendid.
