Just remember that you aren't being a 'good girl' out of compliance or fear, you are doing it deliberately as part of your exit strategy. Remember it when you have to grit your teeth to keep from exploding. It doesn't matter if he thinks you are compliant. It only matters that you know you are not.
And even though you know you shouldn't believe a word he says, pay close attention to those words. I'm sure he's seen a solicitor and he's laid his plans and with his ego, he probably sees very little opposition and/or that he'll easily be able to bully or manipulate you. Let him think that. Everything he says is to manipulate or 'fool' you into falling in with those plans. So for anything he says, you need to listen and think "Why is he saying that? If I did XYZ as he suggests, what advantage would it give him, what disadvantage would it put me at?". Be very alert for gas lighting or anything that may appear to be contrived to make you appear mentally unstable. Consider it like a game of chess, where every move should prompt you to stop and try to figure out your opponent's 'long term gain' strategy.
Learn stalling tactics. If he does happen to sense anything or even if he doesn't, he may very well try to get you to change household finances or responsibilities to make it look as if you pay or do less than you do, he may try to get you to verbally agree to things that just 'don't feel right'.
I know you need time to get your ducks in a row. Just be sure that you're moving ahead as quickly as you can without calling attention to yourself. Concentrate on the things that must be done before you have to 'go public' with court filings (for example to keep the house or to have him removed).
