> When I gave my verbal notice, suddenly there was immediate backpedaling and said maybe something could be worked out. I declined because I don't negotiate like that. If you mismanage a negotiation, there is no do-overs just because you overplayed your hand. The trust is broken.

Agreed. That's like trying to take your money back once you see a river card that doesn't help you in poker.

Just doesn't work like that. Negotiate in good faith or accept the potential consequences.
