Sounds to me like he was just trying to make conversation because he feels that you do not talk to him, avoid him or even ignore him. I am not saying you ignore him at all, just trying to figure out what is going on in his brain.
Maybe he noticed the meds and wanted to know what was going on as an "ice-breaker" type of conversation.
As for the friend--men are not known to pick up the phone and chat like women do to other men. And who knows, maybe the age and diagnosis of the friend has put in your h's mind that life is short, things can happen to anyone at any time.
As for talking to ow for hours. Yeah, my h did that in the beginning because it was an infatuation, thrill type of thing.
