I was being gas lighted and horribly mistreated by my exww when she was cheating. I personally needed the peace of mind and wanted to confront her to at minimum get her to stop the gas lighting and mistreatment. I coughed up several thousand dollars for a private investigator.
It cost a lot but it was worth it. The gas lighting stopped but the lying and disrespect didn't. I felt like confronting my exww was necessary because of how badly she was treating me. I needed some relief and although it hurt, gathering the information and confronting her helped me move on.
YMMV though.
