you've written a lot about how you're not having sex now.
But you've written virtually nothing about how things were when you used to have sex.
Michell's books suggest at one point: if you dont know what works well for the two of you right now... try thinking back to the past, to try to remember what used to work well between you.
You might also try describing, for "your viewing audience", how she reacted during sex in the past. Was it enthusiastic? did she seem into it for HER sake? How often did she initiate? (ever?)
Maybe she always hated sex, but just "went along with it" until she got what she wanted (the ring).
I think that you should approach things very differently, depending on whether you reasonably believe if that was the case.
