<human>: Title pretty much says it all. She gets hypersensitive, got pissed off at me for exchanging mere (non flirty) sentences with a girl on Facebook. A girl who I've known since high school, haven't seen in probably ten years, lives hundreds of miles away, and I do not have her phone number. 

I've never cheated on her, or anybody in my life for that matter. Not the first time this has happened either, so it's time to end. 

She totalled my car while drunk (and quite possibly roofied we think, long story) last year, and I paid $3,000 for a lawyer. She also "lost" $700 cash of mine. She will have a civil suit from the wreck, and said she would pay me back (if she wins) with that. I have no idea when that will happen. At this rate, probably another year from now. It really sucks because I worked two jobs to save that money. I worked literally every day for months. No days off, not one, and four days out of the week, I worked doubles. It's not so much the money it's self, but how much I stressed myself out to obtain it

Should I hold on a little longer and get my money back? Or just count my losses and move on?

Can you condense the text into a few key points?
<bot>: gf goes cray, we live together, she owes me $3,700, and have to decide to wait it out or just take the loss as lesson learned.
