Why did he leave me?

Everyday she wondered why he left until one day he came back. Everything was going perfect, they talked everyday, he constantly told her he loved her and then one day he just disappeared. Why she thought why? When you love someone you just don't leave, you at least sit them down and talk to them, but that wasn't the case. Not one bit. She cried herself to sleep every night wishing she was on the phone with him but she wasn't. One day she found out that he had another girlfriend. How could he move on that fast? It couldn't be, but it was. On August19, 2008 he called her after a whole month went by. She never would have thought he was going to come back, but he did. he told her how much he loved her and that he just moved on off the rebound, because he didn't think she really missed him. As much as she tried to play it off she did, she missed him too much. Everything was going smoothly again. Him and his new girlfriend broke up because of her, she didn't really mean for that to happen, but it did and honestly she didn't care because she loved him. They argued a lot, but they always made up, and that's how she knew he still cared. People asked her all the time why do she keep taken him back, but it's unexplainable. On January 10, 2009 they stopped talking. It lasted for about a month, until one day he called again and told her that he missed her. He told her that he try not to make it seem like he cares because he doesn't know if she feels the same way, and she needed him to understand that she dis. He tells her all the time that she is somebody that he see being in his life for a long time, and that's why he can't let her go. He loves her and without a doubt she loves him too. Now the situation is a little rocky. He tells her all the time that he loves her and even though nothing is official right now they still are close. She want to know that he feels the way he use to even though he tells her she wants to feel it again. No matter what other girls come along she still gone be number one. She do everything for him, and lives her life in fear of what happens next. Is he gone be mad at her? Is he gone try to get revenge? She just doesn't know. She doesn't know why he puts her through this, but she just wants him back she can't bare the pain. Too may tears have been shed, and for what? LLLLLLLOOOOOVVVVVEEEE!!!!!!!
