Sorry, C-nut. There will be a woman out there that feels as strongly for you as you do them.
I had a guy I had dated and he did decide that something was missing for him. He didn't feel the same way about me and I did him. We kept up some sort of FWB intermittently for years when I realized how much worse I felt after. I just really wanted to be with someone who felt the same way about me, as I do about them. So I stopped putting myself in that position.
Got to say, for the short time you have been dating, you sure are getting a lot of action. So the odds are pretty good sooner, rather than later, you'll find someone on even, healthy ground with you.
