The only thing you don't want to do... is what isn't working. How about another tact. Tell him you are interested but you don't want to push. It is up to him.

What would be the 270 degree angle? or 90 degree
When things were better, what were they like? What were you saying, and what were you doing? Who initiated?

He MAY be more worried about his age and things going on inside him...and he's putting it on you. I don't know. But don't overanalyze this ... it will make you nuts and won't bring you closer to a solution.
Just try something else. Anything BUT what you've been doing that isn't working. Keep the things that do work.
