Long distance relationship advice???

Okay so I go to college in upstate New York and love in Long Island, which is about 5 hours away from my college. I met my boyfriend in college and he lives upstate. I knew I was going to go home from May-August, but now because of the virus i came home the second week of March instead. I’m thankful we’ll only be long distance for a few months, but it’s still hard. We’ve been together around 4 months, so not super long, and we were just stating to get closer when the virus started. How can I keep our relationship strong from 300 miles away?
