Long distance struggles

So my boyfriend and I started dating during the school year. Everything was great until I had to go back home from college, which is 3 hours away from where he lives. Lately we’ve gotten into a few fights and became more distant. We both want to stay together, but each day we’re more and more distant. If we see each other, we won’t be alone at all because we both have big families. We miss each other a lot and I just want to stop some of the distant feelings. I mean I realize long distance will make you feel distant from each other, but we want to see what we can do to help cut down on that feeling. Any thoughts?
