He is a narcissist and an abuser,proof of this is the mantra that he makes you repeat,also he has isolated you from your friends and no your sole purpose is not to please him.Bdsm without a safe word is not good and dangerous if you ask me.he is not a God.He can hurt you badly and probably will.Note all abusers that commit domestic violence turn their partner's family and friends away from them, so they,the abuser, are the only influence and the partner has no one to turn to and no reality check.Leave him he is no good.
