Exchange program with boyfriend?

I need help. In a few days I’ll be going on an exchange program to Madrid for 5 months with my 2 best friends. I have a boyfriend. We’ve been together for 7 months now, and he’s also going on an exchange program to Spain, but to a different city 3 hours away. A lot of people have told me that this kind of experience is better when you are single, because a boyfriend may pull you back from traveling or partying. Today my mom talked to me and told me the same thing. She wants me to get the full experience. Recently I’ve been feeling like my boyfriend wants us to get more serious, but I want to take things lightly. I don’t know if I should break up with him now or wait until we’re both in Spain to see how things are between us there. What should I do?
