I'm a cynic...she done it on purpose....to give someone else the blame and burden of Brexit impossible. ..Europe have chucked their dummy out the pram. ..they're all stuffed and want bail out..or rather hand outs. The Meps realise the wheels are coming off the gravy train...
I suspect you could be right, I'm not sure anyone will be able to deliver a Brexit outcome which satisfies everyone. Boris and Farage didn't know how fast to get out of the way after the Brexit vote in case they were lumbered with some responsibility in the negotiations and Cameron had had enough of being public enemy No1 without the hassle of Brexit as well!
