It's actually kind of a funny story. It starts the same as any other. Boy meets girl, boy falls in love, boy runs away. He didn't escape because he was afraid, he escaped because what he thought was love, was just another lie he told himself. It seems complicated, but it's really simple. That's the good thing about having alters; when you're about to do something you know deep down inside is a mistake, they'll make sure as hell you don't follow through.
I'm not afraid to admit that I miss you. It's like getting a tooth pulled out. The second it's gone, you feel relieved, but after awhile, you start to notice the gap. And there are days, when you catch yourself missing it terribly. It's going to take a while - she was a major part of my life. However that doesn't mean you should have kept the tooth. It was causing you pain, and even though it hurts, pulling it out was something that had to be done.
