What would be going on in my partner's head?

Hes a shy person, its hard for him to express in detail sometimes. He told me he had to smarten up this year and concentrate more according to his parents. His laptop was taken away and he wasn't even supposed to be on his iPhone to message me. I told him I would support him. I stopped gaming because it was only fun with him. Each day it would be "Goodmorning" and "Goodnight" but in most occasions, we just had small talk. He started talking about how he played the Xbox with his friends and how it was fun. Then he mentioned how the conversations were funny between them. I then realised he had been in Skype calls with other people, but we had not since the start of the year. I didn't want to mention it. He then asked if I could play games with him again, but my laptop had blocked off all access to them. The small talk turned to only greetings, and I felt sadder because he had not invited me to conversing even though I understood he could. The picture of him on my mind was slowly fading away as exams came along. I caught myself and what I was doing after a few days when I forgot to check or send any messages. I felt scared of seeing his reaction or explaining my absence and left it to a week. I immediately felt awful when I saw that he had still sent the messages. He said he was worried. I then blurted out (in text) of how I was sorry and that I was busy lately. To his friend I explained how we hadn't spoken in months verbally. That week he invited me to a group call with all of his friends and my partner. Immediately when my partner spoke, all my feelings of him flushed through my body. I spoke more, happy being there. I was exhilarated to be able to speak to him again. It may just be my anxiety, but i feel that now he doesn't put as much effort into talking to me and i've just tried to patch up my mistakes. But he's the only one I really trust. What do you think?

I think he sounds like a typical teenage boy. Most of them aren't too deep so you'll save yourself alot of despair by not expecting them to be. Go forward with him as nothing ever happened or move on to others.
