I need help almost..

So me and my boyfriend are in a one year relationship, we’re both 15 and Every morning at school I realize how much of a non morning person he is. He is very distant and quiet and nods and says idk to any questions I ask him. I kinda feel rejected even tho its nothing new. He’s only this way in the morning and I’m the afternoon he’s fun and loving. How should I deal with this or make it better? It makes me upset and don’t want it to. I know it’s simple but it’s been on my mind thank you!
