Rebuild the missing context
Assume the recipient will not remember every date, promise, or earlier conversation. For a message about how to tell someone you want to date slowly, use this factual base: refer to what actually happened, what you want now, and any personal information relevant to informed consent.
Say what needs to happen next
State the decision, information, or practical action you need and include a real deadline only when one exists. 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.
Avoid making urgency into pressure
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. Do not make the other person responsible for reducing the discomfort that prompted you to write.
