Long Distance

I’m about to leave for BCT for the Army and my boyfriend is about to leave for college up in New York, we won’t be able to see each-other again until Christmas when we both have time off/break. Any tips for long distance relationships???? I have like ZERO relationship experience and this is the first guy i’ve ever been in love with and I really want us to work out, even after Christmas we still will only be seeing each-other every few months depending on where I get stationed (I am on a 4 year contract and his college is 5 years) PLEASE HELP!!!!! I don’t want to lose him
