I'd really encourage you to try to be more direct. It is OK for H to know you are in pain.
Something like this may get you better results: "I was having a hard time emotionally being near you in our bed last night. Maybe tonight will be different. But, no promises. I need to take of myself, and I guess sometimes that means catching some ZZZZs on a couch."
Notice that there are no hidden agendas, no blame statements. It is a simple straightforward report of what was going on with you.
