Oh, IWW, I'm so sorry it has come to this - and, frankly, happy to hear it has! It's taken courage to get this far, and now he's trying to beat you down. Annie's right.
Whilst you are married, there is no 'his' and 'yours' (I fell foul of that one, too.) That's why it's important to make copies of all account details, properties and shares, etc, pensions and investment, before he realises you're serious and gets hard advice. So do it now.
He also has responsibilities to your mutual DC. The majority of 'family law' practitioners expect to facilitate a mutually considerate divorce: you'd be forgiven for thinking those are few & far between but, in fact, the majority are fair! Not too many solicitors are experienced with manipulative, greedy, piss-taking spouses. Other posters on this board can give you directly appropriate advice; mine, meanwhile, is: take nothing for granted and don't trust "fair"!!
For now, get hold of all the facts - it may take some snooping & deceit - and tell your solicitor you expect an adversarial divorce, what do they advise?
I know you'll receive good advice here :) Good luck. Stay strong & wise, and gather support around you. It will be worth while. x
