Long Distance Relationship Advice

Hey guys! So I'm in a long distance relationship. He is studying in Seattle and I'm in San Diego and we usually see each other every three months, but because of the new presidency we may not be able to travel domestically or internationally (we are both international). That means I may not be able to see him in the next year or 4. Any advice on how to make this relationship less painful? Like long distance dating tips? I already miss him 😭
