Emotions and confusion

So my bf and I have been dating for 2 months now and things have been going pretty good but out of nowhere he’ll get really distant and lately it’s been more than just a day or two and he says nothings wrong and hangs out with his friends all the time. We are both busy he’s in college I’m in high school. I just don’t know what to do because when we hang in person we always have a great time but we only see each other maybe once a week. And I’m usually the one to plan hanging out I just need some advice 😬😂
