Talking about money

Im a newlywed and before married me and my husband split everything and had separate accounts we recently been talking about a joint but also keeping separate account and now that im married I haven't mined completely taking care of a bill for him or us but now he's been questioning me about how much money i have and i have good amount more than what he would probably think but im very cautious about money idk why but im worried about having to share this information ik hes my husband but i dont want to worry about being questioned about money when i choose to spend or not want to spend
