Well Raz,

As a man I think he is feeling uncomfortable going to your counselor because in the majority of cases it leads to the man being blamed or told he is the problem. Facing that is a monumental step for a man. I don't think it is always the man that is the problem, although I know how difficult we can be to live with, but we are usually brought into the situation and even if we are not blamed right out we are always suspect that we will be somehow the cause of the problem or at least not sympathetic to our wife.

It will take a brave man emotionally to go with you, I know i would be hesitant. We men are resistant to any weakness and we perceive counseling to be for weak people . Right or wrong that is the way the majority of men see it. No man wants to be told that his marriage is dysfunctional or his wife is a mental wreck.
We have our ego to think about.

If it was me, I would go but then again I am always up for a challenge. He needs to look at it in those terms and examine himself. Can he stand up to the responsibility of his part in your treatment? He may not be ready to face that.
I wish you good luck in your journey and hope that he will eventually respond.

Have a great day.
