Good luck with everything! As someone who's the "mono", I would guess that your husband may be feeling a lot of the things I did. Give him time and let him work through things in his head, without rushing him. I know for me, it made me think about what was important in my life. My wife was too important to me to just give up without even trying what she wanted, and now I'm in a place where I accept it and in many ways appreciate it. There are many challenges but I think it can be very satisfying; it sounds as though it's something that you are yearning for.
