My husband said he loved me, but he saw me working outside and saved some money. Then he insisted that I tell him the password of the bank card, but I didn't tell him.

You are husband and wife, but you are wary of him everywhere and don't trust him. Do you talk too much? It's not easy for couples to be halfway. If they still guard against each other, life will be really hard. You can have your own ideas, but if you want to put them on the table, why not make them clear? In this case alone, to be fair, what you have done is not appropriate.
