Short answer is: Maybe.
I saw a priest who went public on Facebook about his experience with a fellow priest who targeted him and tried to destroy his priesthood. I told him my story. He suggested I read the book, “The Sociopath Next Door.” It is written by psychologist Martha Stout, PhD, who wanted to help others avoid the devastation of being the target of a sociopath. She cited a study where 1:25 Americans are considered a sociopath. They are not necessarily murderers but the path of destruction they leave in their wake is no less grim.
You can google the characteristics of a sociopath and decide if your partner/ex/spouse has these attributes.
