bellini - your tenacity is admirable in trying to push forward WA and in that way you are very like TM. I too wished it had passed HP on the first round just to have avoided THIS. I too crumpled as much as TM when Cox described that the WA did 'tie' the UK in to the EU with far less 'rights' than the UK would have if they remained in the EU or 'left on other terms'.
I still hoped through Votes 2 and 3 that it would pass through HP and that the UK would 'negotiate' it's way out of the 'ties'. But that didn't happen, and in retrospect, I can see that WA was too flawed and relied on too many 'hopes' to pass.
There really has to be a different and new approach to this - I might suggest but I lay no claim to knowing what this is.
For your own sanity, you have tried to do what you can but anything more that you do won't help the situation.
So please put all your 'massive' into thinking of another way through; perhaps a way that disregards the he said, she said, I am, they are, I think, I know what they think, so therefore I know.
