My DH went through a period of not wanting to try again because of the physical and emotional experience I went through when we miscarried. I was not ready for TTC for a few months afterwards anyway. I think it's important you both discuss what you are feeling. I think my DH tried to be strong for me, which was appreciated, however I think he didn't totally open up because he was so worried about how I was coping - not saying that's the same as your situation, but just wanted to acknowledge it for myself.
