What does this mean??

I’m 16 and my bf just started college close by so we still get to see each other. He told me today that he hates the commute to college so while he’s in the location he hopes to make some friends so he can have fun. I asked him what he meant by fun and he said. Partying and drinking. This worrying me. I trust my bf but I hate the idea of him being somewhere else partying. I was kinda hurt that he said that. Advice?
