Since you have paid in advance, I suspect there is something else going on with your husband than worrying about dance being a 'bottomless pit'. Ask him why he didn't want to continue and at least use up the package of lessons already paid for? He might be finding it difficult and he is somehow feeling threatened by your enthusiasm. Is it possible to continue on your own if he really doesn't want to continue? My husband likes to dance but has no interest in competing so i do that on my own with my instructor. My husband take an hour a week lesson together but I do 1 or 2 lessons with another instructor.
