what do i do? need some life help please.?

what can i do? i have no job, and theres no jobs going at the moment within a 50km radius that im eligible for, im currently living with an ex that every chance she gets, puts me down. and i have no where else to go... and now shes throwing me out, I've examined every part of my life to see if ive done anything wrong... but there's nothing out of the ordinary, i currently carpool her (i drive) to her work and then go on to tafe, pick her up in the afternoon, and so on, and because of this i can feel myself on a downward spiral, that will end in my dead if i dont do something soon... why do i put up with her abuse? because i still have feelings for her that i dont let show, so my question is, where do i go from here?
