<human>: My friend from Washington State flew down to Virginia to live with me for a while. It was our first apartment, so I lent him $150 because he couldn't cover the security deposit. We ended up losing that money, and he stayed with my family for a month. 

Then he moved back to Washington, promising to pay me back later. Then, he told me he was selling his old computer for $450, and sense he owed me $150, I could just buy it from him for $300. I figured, I might as well help him out a bit, and I could use another computer anyway, so I sent him $300 on Western Union. 

He told me 2 days later he didn't have money to ship me the computer and he would get back to me in a few days. Its been over a week and he just started ignoring my calls and facebook chats. What do I do, is there anyway I can get my money back?

Can you condense the text into a few key points?
