Long distance relationship

Past few weeks its has hit my really hard, because i keep seeing my friends with their boyfriends hanging out, and taking cute pictures. I see my boyfriend when he is free, and he'll usually tell me like the day before, this weekend i was supposed to go over, but then we kinda got into a fight about it and he doesnt want me over. He said we will figure out a day or weekend we can hang out. How do yall handle being away for so long and the having your hopes up and then all of the sudden just brought down?
