This is one, I am not sure of. I understand the principal, and to a degree agree with it. I've been involved in martial arts for many years, something my wife has no interest in, doesn't support my interest, and if she had her way I'd stop and never go back. So what thenI just give up something that's part of me because she doesn't 100% agree and support me in it? If I read the policy of joint agreement correctly, neither partner does anything without the total support and agreement of the other? Just giving it up is bound to create as much resentment in the person giving it up as it will in the other if the issue is forced. So what is accomplished out of this?
