Genie, Have you tried the direct route and said to him, "I would love for you to take a shower tonight so we can ML."?
It sounds to me as if he has given up on the marriage. He may not feel loved and has lost the motivation to try to please you. Also, it sounds like he is using his B.O. to punish you for not meeting his needs. Yuck!
Finally, if you subscribe to the Love Languages theory, then you are unlikely to receive Quality Time from him until and unless you are willing to give him WOA and PT. I know it sucks to be the one to go first but what else can you do?
