Sahm, as a woman who was in a 'good' marriage (or so I thought) and had no savings of my own when the marriage fell apart, I disagree. Every woman needs to be able to 'fend for herself' if the need arises. Saving money for one self is critical.
I've been married to a wonderful, loving man now for 30 years. We do happen to have a joint checking account. But it was a HUGE act of trust on my part to do that. But we both decided when we married that, no matter how bad it got, we were not divorcing. And we both made sure it never got bad. I also went back to college and got a bachelors and masters degree in Computer Science so that I could support myself and my kids by myself, if the need arose. That was/is my 'insurance policy' against bad stuff happening.
My husband fusses about money now and then; I never do. We have enough for our needs, plus most of our wants. In any event, long ago I 'assigned' him the job of worrying over stuff. No need for both of us to worry for nothing.
