Choose the right purpose for the message
Decide whether the message is meant to inform, apologize, ask, support, or close a practical loop. For a message about how to discuss sexual health before intimacy, use this factual base: refer to what actually happened, what you want now, and any personal information relevant to informed consent.
Use detail that helps a decision
Include the smallest set of details that lets the recipient understand the impact and choose a response. Make one clear invitation or boundary and leave room for a different pace or a no. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Know what the message cannot achieve
Do not flood someone with messages, demand exclusivity, or use vulnerability to create an obligation. Meet safely, protect personal information, and stop contact when a refusal, block, threat, or deceptive identity is involved. The message can offer clarity, but it cannot guarantee forgiveness, agreement, attention, or renewed contact.
