Hi there,
I have to say (as Knight's SO) that what he described is exactly what we're going through. I do know that men will react differently, and take all the PCOS/INF information in, and digest it in his own way. I know my DH is listening, and benefits from any new information I can show him. I encouraged him to read the TCOYF book and also to visit my RE with me to ask questions and feel that he is a part of things.
TTC is hard on any strong couple. I hope this advice helps. I guess the short answer is that just because he doesn't react the same way you do, doesn't mean he "doesn't care".
