I am in a looooong distance relationship (different countries) so at present we see each other twice a year for 1-2 months at a time. But we communicate every day by Skype, text or IM. Even when we are really busy we will take 5 mins just to say hi and goodnight or whatever. I would feel weird if a day goes by and we didn't do this. I think it's an important part of our intimacy and staying involved in each other's lives and I am glad we are on the same page regarding this.
Have you spoken to your GF about this issue? Has the contact always been like this since the beginning? I think it's important you talk to her if it is bothering you.
Some people are drains and some are radiators... Keep clear of the drains and hug the radiators!
