Z - I get you, I really do. Most of us fall somewhere between all or nothing, but there is really nothing wrong with your approach. As you know, I read through your old threads yesterday, and I know for certain you're not inflexible. That would be the danger of black/white thinking - but fortunately, that's not you.
When you're ready...your next R partner will be the luckiest W on the planet. The kind of commitment you describe sounds like a dream to all of us here. I'm rooting for you!
