I've had throw in the towel days, but they're a lot different than yours. I'm afraid I'd have to bash your husband upside the head with something really large and really hard. Perhaps multiple times. Could this be why I'm still single?
HELLO -- you are about to have SURGERY. Can he not see that you are ill?!
I wish that men's umm -- anatomy -- could just
ONCE be affected the way ours is on a regular basis. A period would have them in bed for a year!

I can't imagine what childbirth would do ...
I try not to man-bash, but guys like your husband make it soooooo hard.

Your bigger challenge is try to make your son(s) a completely different kind of man, one worthy of being someone wonderful's husband.
Hang in there. You've got lots of folks rooting for you.
