Hello jak34232002,
Some part of that message appeared to come accross as a little too idealistic, I'm all for being hopeful, but what do you think you will achieve by telling her you love her, through your voice into her ears?
Unfortunately, at some point she was in love with you, but you wern't in love with her at the same time, and after all the waiting and pining she probably did for you, this girl must have needed a little more acknowledgement than you knew to give and just ran out of patience.
I don't have much advice to give, but sometimes it's better to have loved and lost, this is a lesson for you to learn, love is to be loved, cherish what you have when you have it or you will indeed loose it..
It's hard, but you will get something out of it if you call her or if you don't. I'm afraid if you call her you might just be setting yourself up for heart break.. After all, she is keeping her distance, and has found a new love in her life..
Good luck, be strong, think positive, learn, and breathe deep.
