First things first, speak to a lawyer. See what you’re legally entitled to and how to go about splitting the marital assets.
Next, since you’ll prob have to move to another property while the divorce goes through, start selling off your stuff that you won’t be taking with you. You’ll be downsizing remember, so get rid of everything that you won’t be needing. Keep the money from the sale in cash hidden away somewhere. This way, he can’t touch it and it’s a little nest egg that no-one knows about. Use it for a deposit for your new place. Rent a flat. All you need is a 1 bed or even a studio if you’d be happy with that. Move as soon as you can and press on with the divorce.
Have a look for work you can do from home. This way when you move you can get your Internet set up, work from home and unpack and settle in around that. It will also show any landlords that you are in full time employment and can afford the property. Alternatively, get a job working with others so you can build up your social network as well as have a steady income. It’s depends on what you want to do.

I wouldn’t tell him anything you’re planning. Just go about your business getting your ducks in a row and building up some savings in order to leave. If he asks why you’re selling things just say you’re giving it away because you’re having a clear out. Don’t t tell him you’re selling it so he can’t ask for the money or take it from you.
If you don’t have your own bank account, open one.
Once your divorce is settled and you get your half of the marital assets, buy yourself a campervan and run away wherever the desire takes you. Work while you travel by being online. It’s a big world out there and you’re still young enough to go see it.
