My husband is losing hope

So my husband and I have been trying to conceive baby number 1 for almost 2 years. Just tried our first round of letrozole and got a bfn today at 11dpo. I can see it in his face he's starting to lose hope I can see his sadness meanwhile he tells me all the time it doesn't matter to him if it's just us. I know he's hurting and he is NOT the emotional type. I'm wondering if I'm talking about this too much but at the same time I'm struggling. Anyone else feel this way? I would love to stop talking about it but I see a doctor every two weeks kind of hard to forget :(
