Most Helpful Guy
I am in a long-distance relationship and I'm studing at the University, so often, when I am not with her, I haven' t much time to hear her.
I suggest not to write huge messages, use the moments in which you can call him for that kind of things. (it might put the "burden" of response on him, and the scarcity of time isn't a good friend of it)
Usually pics and not-so-long messages in which you show what you do are pretty much appreciated, also if they do not get an explicit, immediate response.
In general, during the days in which he has free time, understand that he might just want spend a little time alone making his brain rest and then you could talk via voip, watch films together, do deep conversations, and do all those couple-things without being physically together.
Sex could be an issue in all of this if the time is a lot. Try to make at least him think at you also sexually in that case. I'm not a fan of chatting-sex, videochatting-sex and all this shit, but at least make him remember that when he'll come back he'll have you.
