I am almost 100% he has talked about this and stated this point of view. I remember in one of the youth group meetings I attended we were listening to some of his stuff. It may have been a video or an audio message. I really can't remember.
But here is what I remember distinctly, because this mindset stuck with me for a long long time.
He gave the example of being in a life or death situation. (it was either hanging from a cliff, or else they were in the middle of the ocean-can't remember which) Basically Dobson said if his wife and his child (don't know what age child he was referring to at this point) were both about to face certain death and he could only save one of them he would absolutely, no questions asked, save his wife. and that it was extremely important that his son understood this concept, and knew ahead of time that if anything like this ever happened, he would choose his wife. His son had to know that his loyalty laid with his wife and that nothing could ever come above that.
at the time I really looked up to my youth leaders and just felt that they had the most wisdom so I believed this mindset. I don't know why this particular anecdote stuck with me so hard, but it was to the point that years later, early in my marriage (before kids) I asked dh what he would do in that life or death situation. when he didn't say he would automatically choose me, i was really offended and thought that it was an area we would have to really work through-to make sure no one ever came "in between" us. Thank goodness I've had a LOT of mindset changes since then.
I wish I had more concrete quotes or something for you, but i do know it was dobson that said this.
eta I should clarify this was probably in like 1998 and I'm sure whatever materials we had were already a few years older than that at least
