Even if I can understand some Brexit fatigue, I believe this is a short-sighted view, even if they are out of the EU, geography won't change, so the UK will have to keep cooperating with continental Europe. A weak UK, that would become the pawn of another super power, would be bad news, for both UK and EU. I think this is sad that UK is leaving but no matter what, they will remain our ally and partner.
If any positive may come out of this debacle, it's to set a precedent that leaving the EU is a bad idea.
i.e. Despite the shock of brexit causing EU support to rise pretty much everywhere (IIRC including in the UK, but I'm not sure on that one), most italians are still decidedly negative (which is relevant because post-brexit Italy would be the #3 EU economy).
If Brexit were to be followed by an It-exit or even merely systematic subversion, that could seriously undermine the EU. Note also that some of the former soviet-block countries have governments currently that are much more euro-hostile that their populace, and they might well try a to undermine the EU as much as possible as long as they can do so without being voted out.
And furthermore, if some other countries were doubting their options, I'm not sure they'd compare themselves too much to the UK. There's simply been so much incompetence on the UK government's part that it's hard to believe any other country would need to follow their example. A little more strategically played exit might have been a lot less painful.
Well- assuming Brexit happens at all anyhow, which is pretty much anyone's guess at this point.
