last year in january, my dh and i got a horse for our two daughters to ride and enjoy. however, my dh's daughter (my step daughter) only wants to ride the horse, and refuses to do any of the chores involved with the day to day care. my daughter however, is the one doing the mucking out, brushing, feeding, and everything that comes with caring for a horse including the riding. my daughter is devoted to this horse, and the horse just loves her for it.
i personally don't think that my step daughter should be allowed to ride the horse since she won't do her share of chores, but my dh disagrees. am i being unreasonable to say she can't ride the horse unless she agrees to help look after it? what should i do?
