It sounds like Mr.HP has a case of I-don't-want-it-unless-I-can't-have-ititis. Imagine saying to Mr.HP, "I'm turned on when you walk away from me or when you stop caring". Such an admission almost gurantees that your partner will begin to treat you badly to get a sexual response from you.
This may not be as grim as you think. Your H has desire for you in the manner in which you would like it, his timing is just off. What if Mr.HP were willing to draw on his existent desire and reconfigure it into a timeframe that is more acceptable for both of you?
It looks like it's back to the drawing board re: your medical condition. I pray it is resolved soon.
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
