Advice Needed- setting boundaries

[Sam3]

Does anyone have any financial advice on things I need to do to protect myself?

Since my last post I can see that my husband opened a new bank account at a different bank with nearly $75k in it!
For those unfamiliar with my stitch - I'm a stay at home mom. He controls all the money. I get a weekly allowance. I have a little bit of money stashed from before I was married, that could help with a portion of retainer. But I'm really afraid I will need that money if he files & I have to wait to get temp child support.

I was changing my iTunes account today to my own email that he doesn't have access to. And I saw where he has all the secret folder apps, Internet browsing privacy apps, hidden photo apps. Etc.
It all makes me so angry. I know detach. But it's just so frustrating to see apps on the iTunes account that helped him hide his Ow.
