I would never commend someone for exposing their finances or financial decisions and activities to someone, no matter how trusted they think the other person is. There are certain things in life that we don't share with anyone, and this is one of those things. Your life-partner can usually be the closest person to you, and maybe the most trustworthy as well in some cases, but sometimes, it's better to even not be completely transparent to your partner about how much money you make, what investments you are making or have made, or anything like that. It's because you never know, life can change at any time, people change, and if anything unusual happens, you should at least have some security for yourself.

I trust my mother the most in this whole world, and that's because I know she is the most loyal person in the world to me, who would never do anything that could cause any harm to me or anything related to me. But I don't even share my finances and financial activities with her because I don't feel it's necessary. She doesn't specifically need to know how much money I make, where I spend it, how much I save, or whether I have investments in Bitcoin or cryptocurrencies or whether I'm running a casino or whatever I'm doing. She can know about a job that I have just like everyone else who see me working, but they don't need to know my income, that's a private thing.
