She does put a lot of stock in this relationship, maybe because right now she looks back and thinks that's where things started going wrong for her, but i won't blame a gal for her day dreaming and wishful thinking .She hasn't given up on her hopes of reuniting with her childhood friend, but at the same time she believes she will find the exact same relationship at the top as friendship was before the incident, that delusional.
Her mother told her he wanted to surprise her, but he didn't do anything to get in contact with her and when she meet him at the club, the awkwardness was in the roof. So the best course of action is obviously to "ambush" him in his room... It's just too intense for me.
I understand it's not for everyone...
Btw, she isn't the only clinger in this game.
