It is an opinion, if it's not one you like, that's fine. I have been in the exact situation as your step daughter, take it or leave it. I never said you lack Grace.... those are your words. I said, do it with Grace and you all may end up as the best of friends. Perhaps you should read my reply before commenting
I also didn't say you weren't involved....you aren't her parent though. These are decisions your husband needs to make. Bottom line she is a teenager acting like a teenager. She's not being disrespectful, at least not as you have mentioned.
