<human>: Can you provide a brief overview of the text?

I've been dating this girl for 6 months. I love her and care about her very much, and I want her to be happy more than anything. We attend different colleges but are able to see each other a few times pretty much every weekend, as we're only about 45 minutes apart.

However I feel like just about all my time is being used by her. Even on days we get to see each other, she always gets so sad and upset when we have to go and always tells me "skype me asap", even if I haven't seen my family all day and just want to talk to them for a while. 

I've tried hard to balance friends and family and her, and while she doesnt get upset at me for spending time with them, she does get sad and says things like "go have fun... i'll be here... *sigh*".

I do love this girl, she's really great, dont get me wrong. She's just very attached, and wants to skype literally all day when we can't see each other. I just can't find any way to tell her that I need space, because she'll take it so personally and blame herself, and think I'm tired of her.

I just feel slightly stuck.. we have a great ability to communicate and never fight, but I sometimes am scared to tell her things like this because she'll blame herself and be sad, and I'll have to pick up the pieces, with the only way to cheer her up is me Skyping her for a few hours while I come up with excuses to my friends.

Thanks in advance. I just am not sure what to do.
