Roomate search- again

So a week ago my current roommate finally told me he's moving out- in ten days! WTF!?? Not only will that leave me stranded monetarily for this month- he owes me back rent, as well as utilities for this month! Crap. I sent a nicely worded reminder of his obligations, set out in an Excel format, listing costs and payments. I adjusted what he owes for the last month's rent he paid on moving in and he still owes me $403! (not including the utilities) No word from him yet about how he plans to pay me...and still...
As I was heading into my room the other night I overhear (he's talking loud enough for me to hear through a closed door) that he has asked his new girlfriend to marry him, and is planning to do the whole formal proposal at an SCA event we were planning on attending. Not only does he owe me money- he has used the money he owes me to buy her an engagement ring! GRRRRR. Now I am angry- why does he feel it is alright to screw me this way? And why am I trying to continue to be civil to this troll? This will be the third roommate that has screwed me over-do I have that tattoed on my forehead??
One nice thing- nearly a year ago one of my bad teeth began aching so hard I could scarcely see straight- hurt for over a month. I was eating aspirin like they were mints... friends gave me drugs for pain (oxycodone) and still it hurt. Finally the pain dulled to an occassional twinge. I no longer chew hard things on that side. I am continually digging food particles out of the pocket- and it's exacerbated by the fact that I also have a bad tooth on the opposite side, bottom. That tooth thankfully has had a root canal, so it doesn't hurt- just irritates me. I'm constantly worrying the edges of the teeth with my tongue, and I'm sure my breathe is not as sweet as it could be. I had called last year when I was in pain for a free dental clinic- only to be put on a waiting list- and then told there wasn't going to be room for me. I was given a number to call, but by that time, it had quit hurting- so you know the drill. No hurt- no call! Doesn't mean I still don't want it out of my head! Well- last night I got a call from a free dental clinic to be held this coming Sunday- Squeee! I will finally be able to get these damn things out of my head- or filled- or whatever! Yea!
Well- off to fill out more job applications. A girlfriend has recommended me for a position where she works- she an in-home care person- and with my experience in an adult foster care home, I think I could be an option. But you can't get hired if you don't turn in the app! :) I'm also finally going to get my new (to me) computer set up. Now- to breathe...
