I actually did write her once. My STBH sent her a brief note asking her to sign off one of two cars that still has her name on it. He is divorced but unfortunately that wasn't placed in the divorce. She has a vehicle (impounded right now) in her name when she gets out of prison. He asked that she sign off because he was getting another veichle. She sent a letter back demanding that he ALLOW her son to write to her (we've never not allowed him to write) with a consistent pattern established and that he bring their son to see her at the prison.
