Let him go... If you try to run after him he will one, get creeped out, two, play with you (meaning tease and twirl you around his finger), or three, understand your feeling and talk it out with you. Guys normally don't like to talk about stuff like that, but I know a few who do. However, if a guy says he is over you, he is. It is seldom he will give you another chance. Sorry, and best of luck.
The first thing you should do is to inquire about it from him. If it is true that he said all that, then it wouldn't be worth for you to ask him about giving you a chance. This is because you will be living a lie, which is not so pleasing.
