This too shall pass.....
I felt like dirt for about 6 months post TX. It's 10 months now and while I do feel better, I still tire easily and I do have a lot more aches and pains (above and beyond my normal pains-I have really bad TMJ)
He's lucky that he has you and he should realize that the TX was probably hard on you too.
Hopefully he'll snap out of it sooner rather than later. It sounds like you've laid it out to him. Does he do physical labor for work? He has to get back to work!!!!
