How can i get my money back? (long one)?

Back in July I became involved with a man who I later found out is married. I am a college student and he is a small business owner. At one point during the relationship, he ran into financial difficulties and asked for my istance. Prior to that, he offered his istance in helping me to look for a car. I was expecting a big refund from my school, and I told him how much I was willing to spend on a car and he told me to leave it up to him to find me a good car. We live in different cities, but he travels back and forth to do his business, but he was looking in his hometown for the car. I was willing to spend $4G on a car, he found a car that cost $2.5G and he gave me his bank account number and instructed me to deposit that money into his account, and he also offered to take care of my insurance which he estimated would total $500, and at the same time, he asked me to lend him whatever I could to help him in his hard time, so I lent him $1050. I made four separate cash deposits into his bank account, and somehow didn't receive a receipt for one deposit of $850. When I received my insurance papers, I learned that the insurance only came up to about $200. So now his wife appears in the picture and I attempted to stand back, but he insisted that he still needed to see me, and I was foolish enough to oblige. Anyway, recently his wife has been receiving haring anonymous text messages and phone calls. He confronted me about it, but I swear to this day that it wasn't me. Somehow, the wife learned that I was still in touch with her husband and she called me and said that she would have me investigated and take legal action against me if i continued to communicate with her husband, and then I received a text message from his phone (I don't know if she sent it or he did) telling to stop haring him and his wife (I've never called or text messaged her) and saying that I must never contact him again, and that he didn't wish to have anything to do with me ever again. I neglected to say that I did receive the car, it had over 200,000 miles on it and after having it inspected I was told that I shouldn't have paid over $1G for it. When I explained that I had somebody buy it for me, I was told that the person must have pocketed the balance of my money. Which I don't find hard to believe. But about the rest of my money, there was no written doentation. However, the only bank transactions that were made into his account from the location in my town were made by me and would have my handwriting on the slips. I am missing one receipt, but was told that the records can be subpoenaed. These transactions were made back in October. Is there a statute of limitations? And what are my chances of regaining the money that I loaned? Plus the balance from my insurance? Or even the car? I didn't receive any proof of sale or doentation with the car except for the title... I don't know if I should go to the police or call judge judy. I'm new to the city and don't know any body in terms of attorneys, and I don't want to ask around because I don't want people in my business... Can anybody here help me????
