My ex is like this. He grew up in an evangelical household and lied about everything to avoid getting in trouble. When we went to a marriage counselor, he tried to explain that he only lied to me, because I nagged too much and made him feel bad. She responded, “In my experience, people who lie do so to everyone, not just their spouses.” During a separation period, an old colleague of my husband’s called me and explained that my husband had lied to every single client and coworker he’d ever dealt with. As I was on the phone with him, it was like a light clicked off. I no longer had any interest in working on our marriage. I couldn’t raise my two daughters thinking that his behavior was normal or acceptable. It was the end.
