Why did he say that he's your boss?
If you mean your husband has said that he is your boss, then he is either domineering and trying to exercise power over you. A husband and wife are equal partners, though the wife should obey any righteous request by the husband. They work side by side in raizing a family and making important decisions regarding their lives together. Seek advice if things get out of hand.
