Not much I can say that hasn't been said already Rosie - but my sincerest hopes that things head in the right direction. To err is human - we are all fallible. On the bright side, your husband was honest with you in admitting that he punished you in anger - You'll both grow and move forth from this experience - Keep talking with him about it.
Thank you, Fluff. My husband isn't fond of BDSM related fun - so, when we did it that day, I thought he was doing it to please me. When I found out he was actually doing it to hurt me, I felt upset and betrayed.
