Sounds like you are being slightly insecure. Insecurities destory long distance relationships. My ex and I were in a LDRS and she felt insecure about me in college, she was scared of invisible competition from drunk "college chicks". The week I didn't come online because of exams, she freaked out and litterally harrassed me/scream/cried at me, then she broke up with me. You probably are not at that stage yet, and you can still avoid it by doing one simple thing. Let her live her life, stop trying so hard to talk everyday. If you talk all the time, every time, there is no excitement since you are not doing anything except sitting in front of the computer. Go do something fun, come back and share it with her. It will be something new and refreshing, should make her more interested.
