Do I have to pay back deposit after 2 months and the client hasn't bought any material?

I drove from Georgia to do a deck for a "Friend" upon arrival He "Fills" Me in about Him having a Financial situation. Nevertheless, I stated to Him the expenses I paid to get to I Indiana from Georgia and requested those funds back, $250.00. He also paid a deposit of $850.00 to start the deck. It's been 2 months and He hasn't purchased Not Nair item of Material but He's requesting the Whole $1,100 back! What are My options...
