Everyone feels fed up and wants to move forward.
But this is one of the misleading narratives of Brexit; the idea of 'getting it done'. This concept of Brexit fatigue has been deliberately and carefully orchestrated. The truth is, the more ordinary people switch off from Brexit (whether that's out of boredom, frustration or lack of understanding), the easier it'll be to make progress on it.
I can't see the EU refusing an extension if one is requested. Why would it? It is not emotionally driven. For all the talk of it being fed up of Britain's antics and I'm sure at certain personal levels that's true the EU does not make decisions based on feelings. It makes them based on what is pragmatic and least damaging to itself and its members (which of course still includes the UK, for now anyway). That will mean granting the UK an extension. Of course, the ongoing narrative demands that there'll be some posturing around that, and some political specifics to handle especially in France, Germany, Spain and Ireland.
Brexit is a process, not an event. If we leave and I think we will it's just the start. There is no such thing as a 'clean break Brexit'; that's just press- and social media-friendly phrasing to make Brexit sound like a straightforward, definitive solution to an ongoing problem (which is misrepresentation on all fronts).
In reality, the process of Brexit involves the careful and quite boring unpicking one set of agreements built up over 40+ years, and the setting up of alternatives. It will take 20 or 30 years to 'do' Brexit in its entirety, an idea which doesn't sit well with the 'get out, get out now' mentality.
