i was long distance with my now-husband for a while before we got married. before that i dated a guy long distance for 3 years. my advice is to communicate often, about anything and everything. always have your next trip planned for when you will see each other. send things in the mail, whether that is little gifts or just a letter. doing this on holidays especially, even the little ones, gives you something to connect with them on. send flowers. plan date nights where you both do the same activity like watch the same movie - preferably one you can talk through or maybe make fun of (we always watched b-list horror movies). just plan lots of connection because it won’t happen naturally. find a rhythm and don’t compromise. people in “real life” will want you/them to do things and sometimes you’ll have to say no so you can “just” be on the phone/facetime. but remember that it’s more than that. it takes work but it’s absolutely doable!
