Call the cops, keep her laptop & box. Or play dumb, if you can copy her history file. Txt her & tell her u have to leave house, make a believable reason. Go to cops. Show them the proof. Maybe they can fake your death & catch her. I seen a sitch on ID - different scenario-the wife hired a undercover cop to kill her husband. They faked his death, Etc. But fight whatever you do. Dont run.
