I did not vote because, although legally British, I have neither lived nor worked in Britain. (I am Kenya born and bred and 30 years ago moved to Spain, where I have lived ever since.)
However, I did look at the issue dispassionately, ignoring the political rhetoric, and relying on pure logic and unbiased thinking.
For my own personal gain, I would have been better off if Britain remained.
For the overall, long term benefit of the UK as a nation, it was better to leave.
Why? For a start, the EU is dedicated to tighter and tighter integration of the different ststes within it. One of the major steps towards this was the introduction of the euro, a very useful currency. BUT...
The euro needs a central bank, with a single official interest rate. Within 10 years of its becoming the single, official currency of the majority of the EU states, a serious problem emerged. Many states, especially the Southern ones, needed a higher interest rate, to curb irresponsible borrowing to finance political ends, such as socialist parties promising more welfare and higher benefits. Also, massive borrowing to finance speculative schemes, such as the building projects that were springing up everywhere. However, the industrialised Northern States needed low interests to boost investments in manufacturing, and the (northern based) ECB supported the latter. The result was the meltdown of Greece, and the financial crises in Italy, Spain and Portugal. Even now,these countries are in financial straits, and populist political parties have gained a large share of the votes in various elections.
Sooner or later, the euro will have to schism, or else the individual states will have to give up even more sovereignty, and accept the status of "poorer regions" within the EU. (A similar condition exists in the USA, with some states noted for poverty.)
I know Britain is not in the Euro zone, but it would become sucked in anyway. So the more distance Britain can put between itself and the EU before the euro collapses, the better.
There are many other factors also. Tate and Lyle was destroyed by the EU, in an attempt to protect farmers of sugar beet, imposed harsh tarrifs on the import of cane sugar, plus quotas. Tate and Lyle, the thriving company that gave Britain the Tate gallery, was unable to import sugar from the plantations it owned in the Caribbean, and eventually sold it's name and estates to an American Corporation. It now trades in Britain as a much smaller company, with an almost similar name, and sells mainly beet sugar. However, Mauritius, being technically an overseas extension of France by some sort of legal jargon, can still easily export cane sugar to the EU. Then there are bananas. Where has the variety gone. Then there's New Zealand butter and lamb exports to the UK - screwed by the EU. The list is endless. The UK is suffering a slow death by a thousand cuts at the hands of the bureaucrats in Brussels.
Thus, ignore the rhetoric, ignore the short term problems and look to the long term. Britain needs to leave before it is utterly emasculated.
So there you have it. If there were ever a second referendum I would advise:-
For immediate personal gain - vote remain: For long term benefit - vote leave.

I voted LEAVE and was proud to do so. Looks defiant at remainers here!

I voted remain. At the time there was so much misinformation and lies that it was hard for me to know what was best. Looking back now I am 100% sure that I made the right decision. Leaving the EU will be a disaster, in fact it already is, but the truth did not come out until after the vote. I expect many other people experienced the same confusion and I would bet that very many people now regret voting for leave.

I just hope we get a second referendum on the final deal - maybe at that point we can turn this around.

Didn't vote but if I could id vote leave

I voted remain, but with some reservations. I don't think either side really went into any real detail, and it was one question, with no info on potential consequences, one way or the other. Then to hear that Cambridge Analytica were involved - well, I knew this was going to be a dark and dirty process. And after Channel 4 News' sting on them recently, I was proved right. A total subversion of democracy, and manipulation of people. Thoroughly nasty....

Every time I see her repeating the same old lines I just shake my head thinking: who is behind her and this mess? If I were a conspiracy theorist I might be tempted into thinking that it's some kind of billionaires club that pulls the strings.

I didn't know I could vote, so I didn't. But I would have liked to see them remain...the earth is now a global world, and nothing can change that. Despite what so many people apparently desire, we can't go back, only forward. Progress is inevitable, whether wanted or unwanted. Fighting to keep the status quo or even return to a "better" time is futile. I think humanity would be better served if we embraced the future instead.

I voted remain because the sciences (and also research active areas of the NHS) receive very substantial funding from the EU, far more than parliament would offer us I'm sure.

I did vote Remain and terribly upset about May triggering the Article 50. She shouldn't have done so. I'd love to live in a world of unity and cooperation instead of this divided world increasingly devoid of empathy and understanding.
