No relationship is perfect. A long-term relationship requires constant effort to understand each other, fix misunderstandings, solve problems and continue to grow as both individuals change and evolve. How we deal with our misunderstandings is the focus of this community. Join us to find support, get advice, and share your experience with your relationship.
Wishing you luck with the therapy, Patti
