I think this sort of a thing happens in every marriage. Neither of you are wrong. You just had different expectations for that night. I know you were hoping for a stronger reaction for him. Often times, when we plan things out in advance, they just don't work out the way we imagined them in our head. It's normal to feel disappointed. You just have to do your best to let it go and look forward to the future, though. Dwelling on it doesn't accomplish anything.
I can tell that your husband is trying because he offered to take care of you and wanted to talk about it afterward. I wouldn't take the comment he made about how he would have waited the night before too personally. My husband sometimes wants to space out our time together so he can fit in his video games. I'm the same way with some of my hobbies as well, so we each try to accommodate the other. If it really bothers you, you can talk to your husband some more about it and see if you can work out a compromise. But you shouldn't take it as a sign that he doesn't love you.
It's always good to talk about things before they get to the point where you're really stewing about them. I know it's hard some times, especially when you're afraid to stir up trouble. You also had the added element that you were already feeling shy about putting yourself out there in the first place. It might have been better if you'd discussed things more the night you were upset, but you did the right thing by discussing them the following day. Now you'll both have a somewhat better understanding of what to expect from each other when you're in this situation. Hopefully it will work out better next time.
“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy
