I do not ever ask my husband about savings that he make and do not interfere in any financial decisions that he makes... am I doing it right, or I should start participating in where he is putting money and all? As I have seen my friends know where each and every penny of what their husband earns is going.

it all depends on the kind of relationship you share with your partner. you can ask him about his earnings, but i wouldn't say it should be in an interrogating manner. there are many couples who do not share every detail of their income with their respective partner, but have a joint pool for family expenses and savings.
