A mother and daughter were estranged for 4 years. Now they're on good terms, and less codependent.

• Lindsey Glass was estranged from her mother, Leslie, for four years.
• They reconciled after going no-contact and wrote a book on advice on how to do it.
• They reconnected slowly, building a sense of safety before diving into their issues.

Lindsey Glass was in her mid-30s when she stopped speaking to her mother.

Glass and her mother, Leslie Glass, ran a business together called Reach Out Recovery, where they both wrote books and created documentaries on the topic of rehab after Lindsey became sober in her 20s.

"Here we were, writing dozens of articles about family dysfunction while we couldn't manage our own relationship," Leslie Glass, 79, told Business Insider.
