I think in your situation, you don't have to go dark. I think if you want to respond to him go ahead. What would you do in "normal" circumstances?
I think the space he needs is simple: NO R talks, he's done with that and probably never really wanted to get into it in the first place. Second, lay off the ILYs for now.
Keep up with the cuddling. Maybe don't ask him, just do it. He's been relatively responsive to it. If he sits in another chair, let him. Make it clear you aren't bothered by it.
But I think you can agree, he needs some emotional space for sure.
Maybe you sexy up a bit? Make it a little more spicy? I think too often we become blah about our sexuality and don't think enough about it. Some sexy panties and bras go a long way....put them on and "forget" something you need in another part of the room and walk past him. Make sure he sees you. Sneaky but hey, everyone benefits!
