Because she hasn't shared that hurt, doesn't mean its not there, or is about YOU.

Fact is, you can't handle what she puts down, and a greater fact is YOU don't know why she does what she does.

Yeah, that's true Talainiman, I don't know. Wish there was a way to find out. Might help make things easier to deal with until Im gone

Ask her, you have nothing to lose. She is already pushing you out.

Don't worry about the whys & her.
Just your plan.

"How badly she treated her ex-husband, how much of a drama queen she is, how controlling she is, and so much more. Everything she said just seemed to fit"

Sounds like you already know the whys. Half of them anyway.

If you choose to ask her, do not allow anything she says to change your plans to leave.

Her issues appear to predate even her marriage. Which means her emotional dust storm has been raging for quite awhile. It is not something you are going to be able to fix so don't try. You can encourage her to get help, but you cannot be that help.

You have your own emotional dust to clean up so you don't end up with your own cycle of self-defeating behavior.

Some thoughts on the job front: Have you looked into maintenance work at an apartment complex, trailer park or church? Sometimes they will have live-in positions.
