is my boyfriend going to leave me?

Okay so we haven't been dating long at all about 2 months but we've known each other for a year. We are madly in love with each other and he always tells me how I have his heart and I have the power to break it. I'm currently attending a university as a freshman and he's attending a community college as a freshman this year we're about 40 minutes from each other. But next year he'll be attending a university about 40 minutes away as well. I'm just worried once he gets to the university he's gonna say I'm holding him back or he's gonna find more attractive girls or blah blah blah whatever guys excuses usually are. I know that's not until next year but still I think about it because I love him so much and I don't want him to break my heart. Would it be weird talking to him about it now how it worries me? I mean if we're in a relationship until next year that'll be over a year so I wouldn't think he would want to end things but I honestly don't know. I just tend to overthink
