While living with a boyfriend, I gave him $8000.00 that we were to buy a car with. He then decided to buy a cheaper car, which I gave him another $800.00 until we got the money back from supposedly defaulting on the first car. He now tells me the money never went toward a car, but he used it to pay back bills and does not have the money to pay me back. What are my legal rights? Is there any way to get this money back in full?
