<human>: Could you distill the essence of the text into 1-3 sentences?

It was a internship summer fling that became something more after I helped her though a troubled period of her life. 

Once her internship ended, we decided to keep it going long distance while we finished school in different countries. I caved in and broke it off unexpectedly after feeling the strain of our separation. But now the pain I was feeling from our distance has returned in a new way, but I don't know if I'm feeling shame or affection.

We've spoken a few time over e-mail about the situation and it only makes me feel worse about my decision. I am tempted to make an effort to win her back but I don't know if that will make things better or worse for either of us. Should I stand behind my decision, try to win her back or just leave her alone?
<bot>: Broke up with my girlfriend. I want her back, but I don't know if it's because of love or guilt.
