I left Cheshire in 2006. For us the UK under Blair was becoming too much like the nth American state. DD was 7/8 and so it made sense to move then or else have to wait 10 years until she'd finished school.
It's been a mixed experience. DD ended up doing much better in school than she would have ever done in the UK - her primary school had had a bad ofsted report the year she was born and at a local independent school she became a school refuser. She now has a fantastic job in bilingual after sales support working for a multi-national company in Ireland.
Property-wise we lost out big-time. I've also been completely screwed in a foreign divorce, and XH became an alcoholic.
Where I live individuals can be OK, but there is a tremendous amount of racism/xenophobia which has got even worse with Brexit, together with govt agencies misinterpreting the law after the vote in 2018. In 2018 I was told, in English, to fuck off out of the country by 2 blokes in a café and that I had no right to speak 'their' language as well as I did.
Would I do it again? Yes, I would.
However, leaving an abusive marriage to a violent alcoholic, when you don't have enough knowledge of the law, in a foreign country isn't something I'd wish on anyone.
I'm not in a position to come back financially, and the treatment I need for a long-standing health problem is no longer available in the UK.
The region I live in is very troubled, dating back to the war and its aftermath, and I don't think that's going to change. Anyway, for better for worse it's home.
