Regarding texting or phone calls, I have no real need to this type of communication with my girlfriend, I am usually a bit bothered when she texts me and I must reply (I am usually doing something else and it diverts my attention, which is quite unpleasant for me).
With personal contact it is much more complicated, mainly because we see each other once every two weeks for a whole weekend (due to the distance); initially it worked out well for me, but recently (we are 4 months together), I started to miss her a lot, usually after 4 or 5 days of not being with her. Curiously, although I miss her, I still do not have any strong need to write her or to call her. Also, it does not matter how much I miss her, if there is any change of plans of the visit (such as that she visits me, when the plan was that I visit her, or even that she has time to see me week before than planned) I usually get nervous and totally unexcited about the meeting, though I usually find it enjoyable afterwards.
I am also sure, that I would be able to see her every day; once we went for chess tournament together for one week, spending most of the time together and though I did not mind when it ended and she went home, it was a rather pleasant experience being with her nearly all the time.
