I would agree with the other people here. Run for the border my man.
Personally, I've been in this situation before. You've never met anyone like this before who is such this emotional rollercoaster. I think you are living for the drama secretly and maybe the fact that you want to save her also strokes your ego.
In reality, what bond do you have right now with her? Relationships are a 2 way street and all I see is she's telling you all the bullshit she's having with her life. You are trying to support her but what is she doing for you? Seriously think about that. If I were you, I would not contact her, wait it out but do not, I repeat do not bail her out of her situation.
If you do, then she can end up depending on you and do you want that? eg. Hey, i have no where to live, can I stay at your house...or I'm broke. etc.
These are all realistic scenarios from what I am hearing of her situation. You sound like a nice guy, just realize that if you do pursue something long term, it will be a long long long tough road dude and be prepared to put your foot down and stand firm or else you will be sucked into the tornado of her life and spit out. But if you just want to bang her then you should be okay short term.
Do something as simple as write a advantage/disadvantage list about her or even the "relationship".
and her comment
She told me that she was technically still dating the ex, but only until she got her stuff back from his house.
speaks volumes about what kind of f*cked up relationship you could have with her.
