Here is the thing, John.... You CANNOT stop your wife from doing anything!!!
Being the wife side of the partnership myself, this is the big misconception about leading...
You are responsible for your own balance and movement as is your wife. If you attempt to force her to do something or overlead her you will throw her off her own balance and things will become only worse. You cannot dance the step for her. The best you can do for her is give her a good lead and then give her ownership of the step. At first you may become fustrated, but you need to back away and let her do it.... At first this may mean you will not make your rotation, ect... but as long as you try to force it, and dance it for her,it will just not happen.
When my husband and I get into a situation that it is just not working we have our coach look at both the lead and follow of our steps.... Often if not always, we are both doing something that is causing the partnership to break down. Usually, at first, the adjustments feel horrible and it becomes worse.. at first, but then, it gets better.
Trust me, when you let her go and give her ownership it will eventually work itself out.
