Access Is Not Entitlement
History is not a permanent key to another person's attention or peace.
Familiarity can make people confuse access with entitlement. They knew you before the boundary, so they treat the boundary as betrayal.
But history is not a permanent key. Love does not grant unlimited entry to your attention, labor, or peace. Mature relationships can survive a door that closes at the right hour.
If respect disappears when access changes, what was the relationship truly protecting?
