Wow, are there really no women on this thread? I'm with benwm - my husband is my partner in life and I discuss everything significant with him, good or bad. If it is hard for him to hear, or hard for me to share, we would talk about it until it got easier. The point of a marriage is to share life's journey, wherever it takes you, and I would be missing what I want out of a marriage if I kept things to myself.
In our family I take care of the money and he trusts me with it. He hates math and money stresses him out, and he knows I know what I'm doing (I ran my own business for many years before starting to trade). But we still talk about everything and make major decisions together. I think we both are on the high end when it comes to testosterone (I imagine, haven't really tested it, but we're both fairly aggressive and put on muscle quickly), but I'm far more strategic.
Gender generalizations are not a good way to build a marriage, because while there are overall statistical differences in men vs women as a whole, the standard deviations overlap on every characteristic. That means given any two individuals, gender can only suggest wide probabilities on how someone will behave or think, but it is hardly conclusive. For example, a study might determine most women are more risk-averse than most men, but you can't then say any individual woman will definitely be risk-averse because she is a woman. That's just bad math. Similarly, while it could be debated or studied whether men or women make "better traders", that would not predict whether any individual man or woman is likely to be good at trading. On the same token, the positions that "women are emotional about money" or "non-traders can't handle the realities of trading" are similarly unsupportable conclusions (and the first is just a stereotype).
I think what is more true is that humans in general are unhappy when they don't feel confident the people they rely on to protect their survival resources are going to make good decisions with them. And in the absence of that confidence (warranted or not), more information and agreements about risk will create a sense of predictability and control, and thus less stress.
In any case, every relationship is different as every couple is different, and if you are asking what to do on a forum you should probably talk to your spouse instead, and figure out what works for both of you.
