I have to agree with annie here. I must say that I am really concerned for your mental safety here. I am speaking from the Dom point of view, so i am not sure how much help i can be but I will try.
Me and dru had a bit of this trouble not to long back. I will personal take the blame, as i do realize that it was I that lost my way for a bit. I did my best to not take this out on her, and I do hope that I did that at least. When i relaxed what had happened (I am a bit on the oblivious side so that took a bit) I did everything I could do to be the Domme she deserved again. Eventually I came back to myself, but it did take time.
My point in telling that little story is to say that IMHO, I would have to think that maybe leaving this relationship, maybe even just temporarily, might be in your best interest. I would never expect dru to stay with me in a D/s, or any other relationship for that matter, if I did nothing to let her know that she is loved and appreciated. I think that he is pushing him problems off on you and making you feel as though you are the problem, and he is doing everything right. This to me just smacks or borderline abuse at best.
Don't get me wrong, I mean no disrespect to your Dom, I do not know him, have not meet him. What I do know is what you are telling us, and what you are telling us does not make me want to respect this person as a Dom. To quote Torq in part, respect is everything.
Sorry to ramble, but I just have this feeling in my gut sometimes. Ask dru, I am rather protective of Women in general. So *hugs*, I do hope that you can find you way, whereever that may lead you.
