Man, it sounds like you have been through some kind of hell. I am sorry about your fiance, I’ve been in that position before. Being cheated on hurts, badly. Obviously, you are better off without a disloyal partner, but I know it is incredibly painful to find that out by being cheated on.
How do you like Tucson? I have been there a few times, it was okay from what I experienced of it. I have some aunts and uncles down there. If I had the means to do so I would help you out, but I am currently living off the charity of others myself.
So where are you staying then? A shelter or out of your car?
