Both sides need to take a deep breath , step back and say right let's look at this again without the attitude.
It's still raw like any divorce at the beginning , but generally it dawns on both sides there is little to be gained by carrying on the sniping and it better to come to some sort of cordial understanding for both of you even if it's only for a bit of peace and quite and a return to stability going forwards. for both sides.
Not sure if we will get to that stage as things are playing out , sad to see .
UK: we want to leave the EU because we think you smell
EU: okay, but you will have to leave the SM and CU, which will make things worse for you
UK: no it won't because we'll have sovereignty
EU: as you wish, here is the deal
UK: look at this wonderful deal we've signed to take back control
....it turns out to have made thing much worse...
UK: I can't believe you've been so horrible and vindictive, look at how bad things are, you simply must let us renegotiate that deal we heralded as the greatest thing since sliced bread barely 3 months ago
EU: *sigh*
