Iam confused any advice?

So me and my boyfriend have this sweet relationship we were fighting a lot last year but we worked on it so we both are university students but due to some circumstances we won't meet again (we used to meet three times in week)

so lately everything was fine but he start acting weird kind of and get mad for small things (like I've been sleeping early the whole week due to tiredness i study and work)

he start gets annoyed from my friends (there was also problem been caused by people who know us) so its like we are pretending to be separated as if we break up so thats why we also agreed on not seeing each others and the time of our studies is not the on the same days but know i feel like he can't handle it what to do and is it because he miss me?

Iam confused any advice?
