Try to always get in some practice time where your husband leads steps out of the order learned. Many steps can follow others. Play with them! Have fun!
Another tip is to dance with your eyes closed. It helps us followers give up control. If you want to take it a step further (pun intended) try not thinking about the step you are doing. Take a mental vacation while social dancing and just let the lead take you where you need to go.
Good luck to you both.
