I think the best thing you could do, Grey, is step back from this site, put down all the books, stop thinking about trying to get her to change, and just roll with what is happening. For a good long while, like 6 months. See where it goes, let her set the pace or lack thereof, and plan on probably having no sex for 6 months.
Your anxiety seems to be driven by looking ahead to predict the future. If you can just let it go for 6 months, maybe that will give her the space and comfort to relax and figure things out.
But get busy during the 6 months, being an independent interesting person who is not consumed by thoughts of how to be uberhusband and how to get her to change her libido. RELAX.
The grip you have on this issue is probably going to hurt you in the long run.
In 6 months, if you haven't brought it up one single time, and if you've been interesting and independent and fulfilled, then I think you could ask if you could listen to each other about the topic of sex and see how each other feels about it.
