Actually, I agree with most people. A chat room is not a very good place to meet someone that you would actually fall in love with. I'm not saying that it doesn't happen, or that it didn't happen to you.
More than likely he found someone else and has moved on. I know it hurts very badly, but you should move on too. You need to meet someone that you can see, and that you are near. Like someone in your school.
I know my opinion is just that, an opinion, but I hope what I have said makes sense, and helps even a little.
