Re: jealous wife is cramping my teaching style
I agree with both Stephen and Lynn. The problem is inside your marriage, and this poor student has nothing to do with it. If you make her leave the dojo, your wife will find something else to rant about. I am not saying that she is doing this on purpose. She is probably very sincere in those irrational reactions of hers, and that's what marriage therapists are for.
Do you have children? If you do, they are another reason to seek professional advice.
Peace, and good luck.
