Lying and hiding the truth just means you have to live in fear.
Imagine his surprise. He thought he was her fifth husband, but two years into their marriage, he found out he was her ninth. She lied because she was afraid he wouldn’t marry her if he knew. The issue is trustworthiness. Lying about your past creates an artificial foundation for your relationship that will feel fragile, not stable. Being honest may cost you something. Sometimes it’s difficult but better in the long-run to have a relationship built on truth than on quick sand. What good is that?
