Try this on for size. What if you built that bridge simply for you, to prove you can, just to try to love him a little more and practice loving in case there's someone else in your future.
I already know that I can. I did that last weekend when I went with him to visit his family. The whole weekend was about his agenda and my accommodating it with a positive and pleasant attitude. He was pleased and grateful. He responded by anticipating how he might get even more out of me (re: sex), rather than having the desire to reciprocate. (I know this because this is what he told me.)
I probably could, but I just don't want to go through the rest of my life with no toys because H has to have absolutely every one of them, or snipe at me because he doesn't.
