From what I have seen you have been in a very unfortunate situation and you have been used and taken advantage of. I think you are better off now and down the road you will realize it.
As far as money goes forget it. if you took them to court you need to pay a lawyer and what would you get? Did you have a written contract or if it was verbal do you have witnesses who could testify? Even if you get a judgement against them basically it's worth the same as toilet paper. Then you have to hire an investigator to search for assets they might have.Individuals are very limited as far as recouping things. You can't garnish wages or seize property or attach accounts. You might be able to put a lien like a mechanics lean on their property if they own any and get something when they sell if they ever do and have equity in the property.
I would just chalk it up to experience and move on with your life.
