The Walk-Away Decision Analyzer

Help me decide whether to keep negotiating or walk away.

The negotiation: [DESCRIBE]
The current offer on the table: [DESCRIBE]
My BATNA: [DESCRIBE MY BEST ALTERNATIVE]

Provide:
1. An honest comparison of the current deal vs my BATNA
2. Whether I'm staying in from good judgment or sunk cost / ego / deal
   fever
3. What more I could realistically get by continuing vs the risk of
   pushing
4. The signals that say "take it" vs "walk"
5. How to walk away in a way that leaves the door open

Protect me from "deal fever" — the emotional pull to close a deal that's
worse than my alternative. Tell me straight if I should walk.
