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 support someone ending a cohabiting relationship, use this factual base: acknowledge the loss as they describe it and notice the immediate housing, childcare, work, or social impact.
Separate information from interpretation
Label confirmed facts, open questions, and the specific decision that belongs to the recipient. Offer one practical task or a form of company that does not require them to retell the story. 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 attack the ex, push dating, demand details, or share the news before they are ready. For abuse, stalking, housing danger, child risk, self-harm, or immediate danger, connect them with specialist or emergency support. Medical, legal, financial, employment, and safety decisions may require a qualified professional rather than personal persuasion.
