H is a mess, very similar to many of the partners on these boards. He's revealed a lot to you and his indifference and lack of passion also sounds like clinical depression to me.
Thus, you're still stuck w/him as he is until he can figure out "his problems." Yes, your feelings and emotions are truly yours, but he's also in desperate need of discovery of his own issues. Until that happens, don't expect to see much at all from him save from the status quo.
Can you share some of your observations w/his C? Is he still seeing the C or did he ditch that?
Sad to see from him, but really not surprising to be honest. He has his own Everest to climb before he can even comprehend all the work that is needed to reach the summit of the "marriage mountain" w/you.
