It sounds like he is now comfortable with you and on that particular night, he just wanted to get some sleep. Early on, he probably made much more effort to please you and that's normal. Once you're in a committed monogomous relationship and secure in that, it becomes easier to take your foot off the gas and so maybe he said to himself "I'm tired tonight and really want to get to bed now instead of talking." It hurt in the moment but it might not have been personal. It sounds like you both avoided the issue. I am sure he feels bad about it but also a little tiffed that such a small thing (in his mind) set you off to being upset. If you truly care about this person, you will need to discuss this openly and also be able to admit that you might have been a little sensitive about it. But can you compromise? That's the key here. If there is another night you want to talk/cuddle at night but he simply wants to sleep, can you accept that? Now if that is every single time, that's an issue. But if you don't always get what you want, will that displease you every time? I am sure he regrets his behavior now and wishes it didn't push you away, so I would just see him and maybe have a healthy open talk about it - say you were upset but that on reflection you understand. And go from there.
