Going Insane! Please Help!!

What if the person you believe is "the one", told you that she never felt anything when you two were together...She just kept stringing you along? Maybe she isn't "the one", but she is all that I can think about. I altered my life to fit hers. She just wants to be friends. It hurts so much, because I want to be with her. I'm back in Superior and have nothing to do, because all of my support people aren't back yet. "The One" is one of the people I mainly hung out with as well...and she is back too...Actually she is right up the stairs in my dorm, not even two minutes away from me. I know the logical thing would be to get out of Superior, but I weighed my options and I don't really have anywhere else to go, that won't drive me insane either. There is this other girl, but I don't want to start anything with her, if I want to be with "The One" more...it wouldn't be fair to her....I told "the one" that I needed time away from her, before we can be just friends. Which I'm trying to do, but it is extremely hard...Today, I went to Carribou Coffee and just sat there reading...and I still wanted to be with her...I don't like this whole rejection and then be just friends thing at all...Can anyone help me? I'm in dire need!!!
