What can I do to make this work?

Unfortunately you are becoming the victim of a girl who isn't ready to settle down. She loves all the attention she gets from you and unfortunately all those other guys too. She may really like you but isn't ready to give up her other options yet. However her recent behavior suggests that she is into playing games and manipulating you. Do you find yourself apologizing to her even when u didn't do anything wrong? If a girl is really into you they don't play these games, I see my friends do it all the time stringing theses guys along until their done fooling around. My advice just listen to what she wants be her friend but don't expect much else. The more u push the more she will run and make a fool out of you in front of everyone. More often then not once you start to ignore a girl like this they always come running back. Be careful not to fall into that trap again.
