<human>: Can you give me the gist of the text in a nutshell?

Brief background: relation ship was great, we even both spoke of marriage. She is in school and I work. Up until recently we would spend all of our free time together. About a month ago, after a night of little to no communication from her, she called the next day and broke up with me. She said she was stressed from school and didn't have the energy for a relation ship. She also said she still loved me, wanted to talk still and hopefully come back to me once she is able to handle her workload. I of course protest but agree, albeit sadly.
         This was a month ago, mind you. We still talk most days but she seems so flaky now. I have to ask her to call me. It takes her forever to respond to my texts. She's spent the night once since then and bailed on another meet up just a few days ago from this writing. I feel like I'm being needy but this is out of the norm for us. 
          When she did bail recently she wanted to officially "break up" again but still wanted to talk and she still wanted to be with me but can't at the time. I guess what I'm asking is: Should I wait(I want to) and keep speaking to her? Or should I try to move on? And is this a legitimate reason to break up with someone? I feel like I could always find time for the one I loved. And do you think she is lying?
<bot>: GF broke up with me because school is kicking her ass. Wants to come back after she can handle school/life. Am I stupid for waiting? Is she lying?
