State the news without creating a countdown
Give the city or general destination, approximate date, and why you chose to tell them. Do not use I leave Friday as a reason they must answer today.
Protect your exact address and travel details when privacy or safety is a concern. The recipient does not need every logistical detail to understand the change.
Offer contact without making it the point
If you would welcome a goodbye or future contact, say so in one sentence. Make clear that the move does not require them to decide anything about the relationship.
A message can also simply close the information gap: I wanted you to hear it from me, and no response is needed.
- What is changing and when.
- Why you wanted them to know.
- An optional next step, or no request at all.
Do not manufacture urgency
The fact that you are leaving may be emotionally important, but it does not override a block or explicit no-contact boundary.
Use ordinary contact if available. If it is closed and one notice is still appropriate and lawful, a refusable request can carry it. Let silence remain possible.
