The mood is very much for re-joining in the UK.BREXIT was supposed to be the first domino that killed the EU but it very much didn't work because the average European likes a lot of what the EU has done for them. There are critiques sure but its not a dead system.
Depends who you talk to. I have a mixed bag of UK friends, and it's about half-half.
One thing I think myself is that there was an ugly _hope_ that the UK would suffer as a result. A hope which, as far as I can see, wasn't realised. Living in Europe, I saw a lot on the news about how the UK had shot itself in the foot and things were going badly, but when I visit friends, not so much.
