I don't know what to do..

I've recently moved to uni leaving my boyfriend almost 5 hours away back at home. He came to see me a week after I moved up and it was great! Loved to see him and was sad to see him leave. 
Now I've been here a fair while he's coming up again.. And I really don't want him to. He's become very needy and has been getting annoyed when I don't reply straight away (in either in a lecture or out drinking.. Shoot me I'm a student). If I don't reply he's gets that annoyed we don't talk for days.. And tbh I enjoy the silence! 
I'm honestly dreading this visit. He's staying longer than last time as well.. I don't know what do to..
