Thanks for the replies everyone!
To clarify: The reason I'm still here is because of our child, When we were first together I didn't (I know now how stupid it was) consider our separate finances to be a big deal, I had my own income. I assumed he would give me access to money if I needed it.
Once we had a child, I only worked part-time and had to switch from a hospital with 12 hour shifts to a NH with 8 hour shifts closer to home. I thought it would be no problem to return to the hospital later.
Well, the nursing shortage ended! I ended up with very little income, that's when the troubles started and I realized he had no interest in giving us anything, the new home etc.. he promised would never be (unless I paid for it). He balks if I even ask for grocery money. I feel sub-human.
