Account for the relationship as it is now
Use a tone that fits the present relationship, not the closeness, authority, or access that existed in the past. For a message about how to discuss distance after a friend starts dating, use this factual base: use one or two recent examples and name the trust, effort, money, or inclusion issue they created.
Ask without assigning an obligation
Explain what you hope for while making decline, delay, or a different format genuinely acceptable. Ask how your friend understood the situation and propose one change that can be tested. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Keep the ending honest
Do not assemble mutual friends, post indirect messages, or use confidential information as evidence. Stop direct contact and use appropriate support when there are threats, stalking, coercion, or safety concerns. Avoid future promises, guilt, flattery, or nostalgia that imply the recipient owes you access.
