i am going off to college in september.. and my girlfriend will be in high school.. its not to far away - but i am staying in residence... and i will be coming back every weekend... and possibly more depending on my schedule.. but for sure every weekend.. and she knew this before we started going out.. and now shes complaining saying

"its going to be so hard.. its hard enough not seeing your for one day" . . . "if its only the weekend thats only 3 days we will see each other"

she keeps going on.. its really annoying me.. i keep saying its not that bad - what can i say to stop her from complaining
she just told me.. she think i could possibly find someone else
