“I want to remarry my ex-husband, Greg, but my mother-in-law, who is also my neighbor, has made my life a living hell,” says Amanda. “She has thrown dog poop on my yard, she’s put up No Trespassing signs. She treats me like I’m a criminal.”

Amanda says she and Greg were married for 15 years before they divorced two years ago. She says her mother-in-law, Kathy, comes across as a “nice old lady” but that she acts like a “monster-in-law.”

“Kathy has scared me to death multiple times by taking my children without my permission,” Amanda says, one time even leading to a physical fight with Kathy.
