Split a heated draft into a sendable message and a private vent

Split this heated draft into send vs vent.

Heated draft: [paste]
Real outcome I need: [details]
Relationship: [details]
Channel: [text / email]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. SENDABLE version (short, clear, no insults).
2. PRIVATE VENT version labelled DO NOT SEND.
3. Lines that would escalate, with risk notes.
4. A pause rule (e.g. wait 20 minutes) before sending.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, quotes or what the other person thinks. Give a sendable version and, when I've pasted a vent, a one-line note on what you left out and why. This is help with wording, not legal advice. UK English.
