When two (plus family) of you have all that drama and volatility, it is very absorbing and will certainly get your attention. But from what I've read you seem to have a great life, even a happy life, outside of that relationship (although, yes, maybe at times it can be a little boring and depressing being on your own). She isn't going to change. If you want to go back to the fights and being thrown out on the street, then yes, get involved with her again. But really, if even she says "don't fall in love with me yet" then that's one statement I would believe in.
