I have been divorced for two years with joint custody of a 7.12 and 14 year old.?

The other night I was speaking to my 12 year old and after saying good bye he forgot to hang up the phone at his home. I over heard him tell my 7 year old that "daddy was going to jail". I immediately did some research on the internet to see I missed a court date that was about medical co pays that my ex would not provide receipts for. I simply forgot about the date and the court did not post it on the internet like they usually do. I called the court and got the date changed with no problem but I would of been arrested if I did not. I am upset that she told my boys that daddy was going to jail. She continues to put the kids in the middle of our problems. This is not the first time as she leaves emails and other private matter out for the kids to read. My lawyer said my ex would of liked nothing more than to see me in jail.I have fought long and hard for my rights as a dad and will not let her ruin my life with my children whom I love dearly. How can I stop her from doing this?
