Anyone who says "the EU isn't making it easy for us to leave" doesn't understand the real nature of the UK's relationship with the EU.
Imagine you get married and move to your partner's country. You don't know anyone, you don't know the language, but they help you get integrated. Their father gives you a job, their mother babysits your kids, their uncle (an accountant) does your taxes. Their friends gradually become your friends too. And so on, and so on.
Now, imagine that repeated across over 1,000 different connections.
Now, imagine that you and your partner are splitting up. And one of the consequences of splitting up is that you have to give up all those ties that you forged as a result of being with them. If the split can be amicable, you get a little time to sort yourself out, stand on your own two feet. But either way, all those 1,000+ different relations must end as a condition of breaking up.
How easy would that be? Doesn't make a jot of difference what your partner does, it would still be "incredibly different". And the impact would still be "enormous".
Now map that back into global geopolitical terms. We've been EU members for over 40 years. During that time, we have chosen - a sovereign choice, not an enforced one - to integrate countless aspects of our laws, our trade policies, etc. with those of the EU.
Brexit requires we sever all those ties. It's an absolute requirement, not up for discussion. It would be the same no matter which country was trying to leave.
And bingo, it's super-tough. Not because the EU's putting tripwires in our way, and playing hard to get. But because of the sheer volume and breadth of all the relationships we are abandoning.
We. That's the most important word in the whole of Brexit. We, the UK, have taken the independent and sovereign decision to leave the EU. They're not booting us out. They're not trying to ease us out the door. They'd like us to stay. But we said "nope, we're off."
And as a consequence we are suffering exactly as much as it is natural for us to be suffering, giving the complete rupture of all our existing relationships.
