I wrote an e-mail directly to my customer stating that I felt he was trying to cheat me because he did not want to pay the invoice in full. No other party saw this e-mail. It was sent from me to him and that was it.
This guy is now threatening to sue me and I really do not think he can. Does he have anything to stand on at all? Today he e-mailed me and cc'd his attorney. Should I be worried?
