You can keep a door open for someone without standing in it waiting.

Being willing to hear from someone and waiting to hear from someone are different states, and only one of them costs you your week. Open means that if they turned up, you would answer. Standing in the doorway means refreshing a thread, keeping Friday free in case, and reading every silence as a message. The second hands your calendar to a person who is not using it.

Make a plan for this weekend that does not depend on them, and keep it when nothing arrives. You can stay reachable without staying still. If they come back, you will hear about it.
