Would not seeing my girlfriend cause any problems? How often do you guys see your girlfriends?

Ok so how often do you guys see your girlfriend? I don't see her often and its not like she lives far away shes just always busy. I see her once like her every two weeks and maybe I would see her in a week sometimes. I don't know if not seeing my girlfriend would cause a problem, or it would depend if shes ok with not seeing me as often.
