Tips for long distance relationships and stories

Over the summer i met the loml and we fell in love immediately and have such a strong connection. He lives in a different state but he’s able to visit me every holiday and so but when he left today i started crying. I love being with him in person so much but ik one day it’ll be worth it. Anyone got tips for long distance relationships and encouraging stories? He wants to marry me and everything and I know he’ll be loyal.
