So BREXIT is most likely gonna happen then?
Based on past experience, I'd say no. Based on the full-derp that the Conservative party has been exhibiting since the referendum, I'd say 90% yes.
My reasoning is that in the recent past (more than once between 2010-2017), the government went to the EU and said "guys, we need you to throw us a bone to feed our people so we look all tough and powerful". Every time the answer was basically no, except for a couple of scraps that literally no-one in the UK puts any stock in whatsoever. The EU held all the cards in any case and the UK government had little to bargain with. Furthermore, the UK government wasn't in the habit of doing anything particularly crazy like threatening to leave for the obvious reasons being that we have a lot more to lose from leaving than to gain and the party would eat itself alive for doing something like that without some kind of mandate.
So, the referendum was announced as promised (a bone that David Cameron threw the electorate in the 2015 election because he thought he wouldn't have to honour it as he expected another coalition government - instead the conservatives won an effective majority in that election), and the government played both sides of the fence in that referendum (though really their remain campaign was little more than the character Fiver out of Watership Down saying "we're all in a mist! I have a funny feeling in my toe if we leave the EU!": Yet another thing the opposing parties should flay them alive for, for lacking any kind of grit or principle that they can't even get their party to back one side), and brexit won.
So now the conservatives feel they have some kind of mandate, but what does this mean? Does it alter anything about the UK's bargaining position, apart from giving them a 'get out of jail free' card as far as the UK populace is officially concerned if they want to go full-derp and go through with what they've threatened to do and consider leaving the negotiations with no deal whatsoever for trade and everything else from the EU? In my opinion, no.
In a sane world, they would have come to the same conclusion, and furthermore concluded if they went full-derp then the UK public would want them flayed alive for destroying at least half of our economy; the EU takes 55% of our exports. There's no great frontier for us to explore new options and trading partners; we don't have a great manufacturing centre or a corner on any particular substantive market. Our finance sector is envied by various EU countries, and since our finance sector will want to continue to trade with the EU, they can easily move the market of pure maths basically anywhere they like; various financial institutions are already planning to leave the UK once Brexit occurs.
I say "in a sane world", because just like Trump supporters, I have literally never encountered a brexiteer who came out with a coherent idea of what they expect from brexit and why that happens to actually tally up with the available evidence. The closest I encountered to something coherent was based on an assumption that the EU is imminently about to die, which of course there's little evidence for, but at least the rest of his logic was sound. Most brexiteers are acting exactly like Trump supporters, shouting "get over it" and ignoring anything that criticises their thinking, gleefully riding a roller coaster (one supporter I've encountered has likened it to that in a positive way) whose construction isn't complete yet, and won't be complete by the time their car flies off the end of the tracks. I honestly think that if Brexit goes as badly as it looks like it will, most Brexiteers will blame the EU for not giving us everything we want in the negotiations while we give nothing in return.
For me personally, the long-term has some pretty scary uncertainties: I'm on the cusp of signing up for a mortgage because I'm old enough that it's either that or rent for the rest of my life, my wife is German and there's a lot of uncertainty over whether she will be allowed to stay when Brexit occurs, and then there's the economy - if it gets fucked as badly as it looks like it might, then we'll likely have another recession, and during the last one my business was close to going under.
