It's been about 9 months and my spouse is less and less interested in sex. He has ED. He has taken Viagra and another ed drug and this doesn't even help. He won't admit he's not attracted to me . He's OK sometimes with oral sex but even then he loses his erection sometimes. He won't tell me what's wrong so now I'm playing the guessing game.
Any response would help.

Any response would help. We have gotten divorced but are still together.

Does he have any other medical conditions? Does he take any medications? How old is he?

If he has ED, then his problem is physical and has nothing to do with not being attracted to you. However, since you say you're divorced -- there must be SOME distance or relationship element involved here that you're not mentioning. If you've split up and you don't believe he's attracted to you, why are you still together?

Without knowing more, - I'd recommend he talk to a doctor especially if he's taking drugs without effect.
