To add to these ideas, I’ve heard of a 4 bank account system for couples.
Joint Checking where living expenses can come from.
Joint Savings for shared investments. Requires two signatures to move money out.
And then each gets a personal account with their spending money that each gets to do whatever they want with.
Yeah that’s tough when you run into a wall like that. Maybe just reiterate that something seems up, and then if she refuses to admit that, you can at least expand on your observations and why you think something is up. Ultimately, if she still refuses to talk about things, you have a binary choice to make. Tolerate it, or walk away.
