When you've brought up working on the R in the past, has it worked?
This might seem like a 2x4, but seriously; what you're doing right now is working. Keep doing what works, don't revert to things that don't. Enjoy what you do get and above all, be PATIENT.
FWIW, I have a similar challenge as you. W shows affection, but claims no emotional attachment at this time. The confusion is hell. I find that focusing on whatever I get that I didn't expect, and working on continuing to better myself (a HUGE undertaking, let me tell you!) is VERY helpful.
