Am I stupid for saying and thinking I love him?

People like to have somebody to cling on when they get weak. Since you don't have anybody special (at least none that I've read up here) to share anything under the sun with, you find this almost mysterious and fantasy type of relationship very comfortable. Nothing wrong with that although you might be a bit careless pouring out you're feelings on somebody you haven't met yet. We are all aware of the risks of online relationships, right? You're 13, he's 15...maybe it's better if the two of you don't pour 100% of your feelings yet. Why not try and meet up? You haven't seen him yet right? Try to have a video chat with him first. And if you still feel the same about each other, then waiting for a few more years to mature wouldn't hurt, right? If he doesn't like to start a video chat, ask him why. He might not be the only one telling a 'small lie'.
