A "sciopath" is not a widely recognized term in psychology or psychiatry. It may be a misspelling or a confusion with "sociopath," which refers to a person with antisocial personality disorder, characterized by a lack of empathy, impulsive behavior, and disregard for societal norms. If "sciopath" is meant to refer to something specific, please provide more context for clarification.
The symptoms are basically the same for all sociopaths, though a female sociopath may be less inclined to use physical violence. She may be more interesting in humiliating you, especially in among people who know you. For example, she may tell everyone at a party that you have an you lack the proper qualifications for your job, or she may tell friends and family that you beat her up, that you abuse the kids, that you have a mental illness that makes you very dangerous. She may appear at your place of work and throw a spectacular temper tantrum. Like all sociopaths she will try to harm you and she craves power over others.
Tell him safely over the phone that you want nothing to do with him. Dont offer anything else, dont explain why, just end the call. Then completely ignore him. Dont go anywhere he does. Dont give him one inch. You owe him nothing. First of all it would be useful to know exactly what a Sciopath is. Sounds more like you might have someone who is obssessed with you? That doesn't mean they're a sociopath. True sociopaths have a list of certain traits. These traits are often found in people you would never think of as being 'sociopathic'. IE High achievers/leaders etc. It's when a person exihibits more than just a few of these traits, that you are dealing with a true sociopath on the highest scale. Traits include self centredness, risk taking, no empathy for others, blaming others for their own behaviour & sadistic tendencies. These are just a few. Most people often show signs of these traits at certain times.
