When schedules get crazy, you won’t be able to spend as much time together as you did in the beginning, when you were willing to stay up all night just to be together. But, just because you can’t be together, doesn’t mean you can’t desire to be together. It’s too easy to just state matter-of-factly, “I won’t see you for a couple of days. I’m doing this tomorrow night, and then this the next night.” And you do this because you assume by now he knows you wish you were together when you weren’t. But when those, “Wish you were here” or “Miss you so much” texts stop, it’s easy for a partner to feel that his presence is not as desired anymore.
