Sorry for your struggle . You'll find similar sitches and wisdom here.
I used to be a LDW and the things your W is doing sound pretty familiar to me. Overeating fatty/filling foods, wanting to cat nap until time to get up, doing activities that make having sex impossible are all tactics in the LD arsenal. There are many reasons for spouses to not have/lose their desire for sex. Why do you think your W is currently LD?
Your efforts to "get her in the mood" are unlikely to pay off unless you go into it with the attitude that the behaviors you refer to in your post make you a better person and her response to them doesn't matter to you.
I don't mind the sun sometime
The images it shows
I can taste you on my lips
And smell you in my clothes
Cinnamon and Sugar
And softly spoken lies
You never know just how you look
Through someone elses eyes
