Relationship advice

I'm 18 and my boyfriend is 23. We are a secret bc he wants to wait til im done school to tell our families which I agree with. But things are very tough. Sometimes I feel like he can be secretive bc idk his family or friends. Yet he thinks the same think because he doesn't know mine. But we trust eachother. But lately I'm finding a boy attractive. But he's going to Ivy League school in the fall and I'll be a community college. So, booth would be tough. I just don't know what to do. Help ?!!!
