I don't think you can claim fraud since you willingly sent him a MO. You weren't sending money for an item...so where did the fraud take place? Personally since he jumped the gun and filed with PP, you should have waited and let them handle it. Hopefully he honors his part and returns half of the money, but you should have handled the situation differently imo. I know you were trying to be the nice guy and get it straght but tthe potential for this happening should have told you to let PP handle it in the first place since it was his choice to file with PP.
