These are the mistakes I've made in Plan A:

Mistake #1 - PLAN A must have a time frame for ending BEFORE it begins....
Mistake #2 - push for the apologies...and woe to you who get it without true meaning because you will not have true remorse... (though I haven't pushed H for an apology, I've been expecting one)
Mistake #3 - PLAN A is never ever about getting a committment from the WS to do something....

This comment from Ark hit home the most:

People that do plan A well find great freedom and creativity in the doing and giving and meeting of ENs...

people that expect their needs to be met...
flounder and get crushed....
