Long distance relationship...?😞

Madison
My s/o and I are having problems and arguing about distance. 
He and I have been together for almost two years now and he and I both hope to spend the rest of our lives together. Despite that, he and I aren't the happiest we've ever been. He and I both have school and work and get extremely lonely as I can only see him every other weekend, sometimes every weekend.
I know it may sound like it's not a long time away from each other, but I am miserable Being away from him. He's my best friend and he brings out the best in me. 
Any ideas of how to make the distance easier?
