I don't know if I like this guy, or not. I feel very confused, and I know you can't help much, because this isn't really a question. But can you please tell me if you have ever experienced this? Some stories or whatever?

If you like someone, you would know that straight away, normally without having to think it over and over again. So you already know the answer to your own question.:-)

If you force yourself to get an answer it'll never come. Let the answer come to you naturally over time and you will know if you like someone or not. For now, get your mind occupied with something else.
