Lavender, I'm also having an 'international' divorce here in the UK to a man who absolutely refuses to co-operate with the divorce he instigated! So I know how the complications that faces - specifically getting any money out of them.
However, if you want to live in the UK without this man, then let him do some very silly things, he won't be able to come back here ever again without being arrested. That is how scary the law can be. Also, freezing orders and injuctions can pretty much be applied world-wide. Unless he's aiming to spend the rest of his days in North Korea, most countries have reciprocal agreements with the UK.
For you, you're stuck in this hideous 'parallel universe' just like the rest of us getting divorced: it is terrifying.
Turns I married the 'master of the universe', apparently, but here on planet Earth, we merely have a legal system that can be a very, very effective way to help bring them down to earth. It just takes a long time for that to happen and it's stressful.
You want a life free of this man. You can have that.
It's a horrible, horrible process but it ends. You need to get it underway because the sooner you do, the sooner it ends. Ask your solicitor for a Timetabled Divorce so that you know exactly what you have to do and what he has to do. Otherwise this will just drift on and on.
And anything "he says" should be taken with a pinch of salt, mine has been saying he's doing x, y and z since May, that he's entitled to a, b and c. He is merrily disposing of assets because he can. Again, this is now under the court's attention too. It just takes time to get to the courthouse, but once you're in the system, it does not let go.
The rules are the same for me as they are for you, as well as these master of the universes.
