I'm English but live in the US. My family are in England & I often think I should move back at some point but apart from family & friends (which obvs are very important) there's little reason to live there. It does seem like a depressed run down place. I was a Remainer but came around to supporting Brexit after the fact. I think in the long run it will be positive that we left the EU. It won't be for a while yet though & I see myself staying in the US for now.
