Well, the letter sounds very nice - just be prepared for the possibility that H may have to get more forceful and say things like "Please do not EVER call or contact me again, I love my wife and I want you out of my life you manipulative b!t@#". It was only after OW continued to contact my h after he asked her not to that he began to see her manipulative side - then he sent her a final assertive letter and she went away (thank you God).
