I am 17 years old. I dated a guy named Matt for about 3 or 4 months. We have been apart for a while now. My relationship with him, had some good times, but also a lot of really painful times. I am in an excellent relationship right now with another guy. But for some reason I can not stop thinking about Matt. I mean none-stop! I dream about him, I think about him 24/7! Why? How do I stop this? Do you think he might be thinking of me too?
