Hi,
The last post was in May and so, I don't know if there's any point in putting in this reply.
Anyways, here are my thoughts.
She initially wanted to take a break so that she could concentrate on her studies. I implied that she still wanted you two to be together. That's fine then. On the other hand if she said she wanted to take a break by breaking up, then you should worry.
You then implied she felt she needed to experience life or learn more about herself. That now meant she originally wanted to end it but didn't have the heart to tell you. Did u ever ask her if she knew you were the right one for her or not?
