Should I be upset/angry?

So my boyfriend and I have been together for about a month and a half. He goes to school in NY and I go to school in RI, but we are both from NY. So yesterday he told me that he has been thinking about me having to go off to school and how that would affect us. So he told me that while I’m off at school we should just be friends incase a “better version” of ourselves comes into our lives, and that once I’m back in NY we’re back to being girlfriend and boyfriend. This upset me a lot yesterday. Am I wrong for being upset? Does this sound like a normal idea?
