Dawg, I would encourage you to (if you haven't already) normalize your W's feelings (or lack of feelings). If you can reassure her that it is very understandable that her feelings could take a while to return, then you might be able to help her reduce her self-imposed pressure to have sexual feelings for you - which could actually help them come back sooner.
Sometimes people just need to be reassured that their feelings are OK. Her lack of sexual feeling does not mean she does not love you, nor does it mean she will not regain the attraction. This can be a very normal response in any R at certain times - help her see that, OK? Your understanding and ressurance (and giving her space as you already have planned) could help a lot at this point. (And if you are already doing this - great for you!!)
And if I were to give you really bad DB advice , then I'd encourage you to point out as often as possible, how very, very worried you are about her lack of sexual feelings. That you're even wondering if your M has any hope if she continues to feel that way. Now, that would be extremely bad advice on my part and very unproductive responses on your part, right? So, that's under the "don't do" category.
You've got some good pieces to build on - put a bit of patience with that and continue to enjoy each other step by step. You have my support,
