Check who should receive the message
Confirm that you have the right person, the right role, and permission to disclose the information involved. For a message about how to resolve conflict with a friend who is a roommate, use this factual base: use one or two recent examples and name the trust, effort, money, or inclusion issue they created.
Separate information from interpretation
Label confirmed facts, open questions, and the specific decision that belongs to the recipient. 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.
Use formal help when stakes rise
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. Medical, legal, financial, employment, and safety decisions may require a qualified professional rather than personal persuasion.
