There’s a difference between privacy and secrecy in a relationship.
It’s okay to keep some things private from your partner. They don’t need to know every small detail.
Secrets, on the other hand, can be toxic. When something private is coupled with shame, it becomes a secret.
Secrets are kept hidden. The great psychoanalyst Carl Jung called them “psychic poison.”
So respect each other’s privacy. But don’t keep secrets.
