Former Manager sharing detailed information about termination with buddies.

I was fired from a position offshore recently. I was told that I was warned ahead of time about issue that I was having at work but I was never counceled or warned. The person in charge would tell everyone on the platform everyday that I was a spy for the government and to watch out for me. I asked him to stop repeatedly but he would not. I was fired for reason of being on the phone arguing with my wife on my off time in my quarters off the clock. Now there is a manager from the previous company going around telling people that I know details about me being fired and it has caused a lot of stress and arguments between my spouse and myself as well as her family. There is no reason for this person to be sharing these details with people that I know on his off time. What can be done with this person. It may have already caused me more harm other than the mental issues and family stress. I have been looking for work but keep getting turned away for reasons unknown. I want this to stop at once. What are my legal options? Can I press charges against him for sharing personal information with people outside of work? Can he be served with anything that will make him stop running his mouth?
