After the Brexit vote I moved away from the UK, one of the reasons is my partner is from another country and there was a general feeling of hostility in the air ... I can empathise with those leaving, and if it were me I'd be doing the same thing!
FWIW making a new life has been very rewarding and we're in a much better place, moving can be about making something new more than losing something old. Now when I visit "home" I feel very glad to have got away.
