Is he being controlling?

My boyfriend and I have been on and off for almost a year now. We just got back together again and have started staying nights together (which is really new). However, it doesn’t really work well for me because he’s serious about his sleep at night and I am a night owl so I have trouble sleeping. The first time I slept at his house, I used my phone and he started sending weird texts the next day about how I must’ve been texting someone and telling them I felt trapped with him and how it made him feel guilty or something like that. I also notice that he does try to snoop a little sometimes. The next time, I didn’t even touch my phone because I was falling asleep as soon as we got to his house. This time, the 3rd, I laid down before him because he was watching a movie. So I started watching something on my phone while I was waiting for him. When he came into the room, he started saying something about it. I don’t remember exactly what it was, but it was basically to the effect that he didn’t want me to use my phone while sleeping with him. He was saying that he felt it was late enough in the night that I didn’t need to be on my phone, to cuddle with him and go to sleep. Which ok, fine. But when he was saying it was “too late” he seemed genuinely annoyed about me wanting to be on my phone and then he made a weird joke about how he’s “grounding me from my phone”. He went to turn a light off and my phone had a notification so it turned on and he said “I was only up for a few minutes. You’re already on it again?”. I said “idk why you feel weird about it” and he changed his tune and said he didn’t, he just couldn’t sleep good with the light. But I’ve been using my phone throughout the night and he hasnt even woken up once.
