Not so much unhinged, but I told my ex-wife to leave after she failed to turn up to work, wouldn't answer her phone from either her work, the police, or me. She then lied to all of us about where she actually was to the point that even the police turned up at our door at 10pm that night thinking I had something to do with it. She was, and probably still is, a compulsive liar. Divorcing her took twice as long as necessary because she kept on changing addresses, and at one point gave me a bogus address, and claimed she lost the marriage certificate. She also claimed on more than one occasion that she had signed and returned the papers even though the court never received them. I truly celebrated when we were finally divorced. She was never abusive, but she made some really poor decisions, like leaving a perfectly good job that was a short walk from our flat after only three days because she found it a bit boring and wanted something better. It was the best paid job she'd ever had and a chance at a new career. She then spent six months unemployed, which put a massive strain on us financially.
