Girlfriend is Studying Abroad?

[Harpua89]

My girlfriend is studying abroad in South America for 7 months....We have been skyping for 4 months and she now tells me that she wants a break because she feels guilty that she is not able to commit emotionally to our relationship. Before anyone accuses her of just wanting to slut it up, she is actually the nicest most innocent girl I have ever met...(She is from the midwest)....So i don't think she would ever cheat on me. After she told me this I messaged her saying that "we need to talk"...she told me that she stayed up all night worrying about what I needed to talk to her about. So obviously she cares about the relationship. What im trying to say is that if you girls were studying abroad would you ask for a break with your boyfriend? Does a break always mean cheating? We have a great relationship, she wants to keep our status as "in a relationship" but just says that with classes, sightseeing and traveling she doesn't have time to be emotionally involved. She told me that she misses me and wants to be with me when she gets back, its not like she is leaving me, she says she still wants to talk on skype, but just doesn't want to feel like a bad girlfriend when she can' talk. Please be honest ladies, does this mean she wants to be with other people? or can a break honestly be about what she told me? (guilt, etc.) I really care about her, and I know she cares about me.
