Hello there😊 First off stop worrying something is wrong with you, this is basically in the human nature I could say. We tend to ignore the ones that pay attention to us and run after the ones that don't maybe because we want to know why or I don't actually know the reason for that. Girls in general (don't fight me and insult me on this please) as studied tend to go for mysterious guys and the hard to get ones rather than the simple ones. You just figured it out enji it happens to everyone, you're okay nothing is wrong with you.
