My advice is to open a savings account separate from your husband and start saving. Usually, I don't condone deception but this is an exception because you might be dealing with a angry spouse who will cut off all financial resources to you if you decide to divorce. I was a stay at SAH mom for 35 plus years and found myself with no financial resources, only resource was my ex. If you are able to get credit cards under your name do so and don't use them unless necessary. Have your finances in tact before you decide to leave or stay.
