M, I told my H something similar recently. I didn't go into feelings as much as you did, but I did tell him that I knew I could change course anytime I wanted to.
I could be totally off-base, but I think in some sitchs they need to hear that this is not what we want (or wanted) but we are doing what we are doing today because we choose to and we can choose to do something else at anytime. To me, it's like saying I'm here for you at the moment and I can tolerate this limbo for a while, but this isn't a never-ending scenario.
All of that stuff about this is what you wanted and what you need and this will be beneficial for S is his way of justifying what he's doing, easing his own guilt and putting the responsibility for the sitch on you. Projection, as HW said.
