I can so relate. When XH was getting his stuff from the house he kept telling the two policemen that were there that he had bought everything in the house and supported me for years. I should get nothing. XH has been unemployed the majority of the last three years and I always made more money than he did. He always has to put on a show. My only comment in front of the police "Your unemployment checkstub is on the kitchen counter, be sure to take it." Not nice but he aggravates me with his outlandish lies. He even went so far to tell our mutual friends that the reason I filed for divorce was because I am lazy and don't want to work so I am looking for a rich husband. These people know he has been unemployed and know I make more money than him. He makes a fool out of himself with his lies.
I also get the outright lying, "forgetting" to tell me something, or swearing he told me and I must not remember.
As for telling him the reasons why you only want to communicate by e-mail, don't do it. Any time I have told XH how hurt I am by his behavior and that it pains me to talk to him he called me MORE.
