i would give my right arm for a ILY right about now. Pick up the PMA a little. Remember what we talked about before, maybe his idea of low key is with you. Don't fall back into your own trap again.
He is probably still down because he can't do the things he did before, because of injury. Take that into consideration, sounds like a little depression on his end. probably looking to find himself again and to feel useful as he probably is in the mindset that he is not what he used to be. I know you have hard times accepting some things, but put yourself in his shoes, what if you couldn't climb anymore, bike, etc.... how would you react internally. Think about it. i see he loves you more than you realize, open your eyes and make the time for him, something he is comfortable with.
His ILY should mean a ton to you right now, do not let it slip away. OK
