Prepare a practical written no-contact plan with boundary wording, ways to handle urges to reach out, and a simple schedule for the first days or weeks. Share the breakup context, any communication you still need to manage, and what tends to make no contact difficult; the draft can then be revised as your circumstances or goals become clearer.
This is planning support, not a reminder or monitoring service. If safety, shared responsibilities, or legal arrangements are involved, adapt the plan with appropriate trusted or professional help.
