There's scope for different, perfectly acceptable behaviour patterns on this.
For me personally, I'm very much in the same school as your boyfriend on this. When I'm physically apart from my girlfriend I have minimal phone, text and online contact with her. When we're together it's a case of being very much the loving boyfriend. It's all about when we're together we're together. When we're apart we each have the space to get on with our lives. I see this as very much a long term thing to avoid burning out in the long term.
However some people are very much in the school of wanting to keep in touch on an almost constant basis. That's fine too. There's no right and wrong on this.
So what we have is some incompatibility on this issue between the OP and the boyfriend. I don't think that this issue on it's own is enough to end the relationship. It all depends on whether this is just one of several things - one or more of them more important than this one - where these 2 people are incompatible. Whether this is just an isloated issue. Or whether this is the tip of the iceberg.
Even then, with the OP being at uni, it would still be a valid decision to dump this boyfriend and look for and get other romantic partners from the uni. Just to see what other boyfriends are like. To treat uni as a chance to learn as much as possible about relationships as well as the chosen academic subject.
