If you want co-operation on the domestic front:
Be specific and expect results!
Your husband doesn't know what "You have to help me" means.
Does it mean help carry in the groceries? Does it mean follow you around and help with everything? Does it mean something in between?
Tell your husband, "Honey, I would really like it if you helped me carry groceries in from the car every time I get home from the store."
Men are far more willing to help with a specific task, but when "Help!" is an ongoing command, they just shut down.
Be specific and expect results.
