Why am I jealous!? I don't even like him!!!

It's kind of like the movie " my best friends wedding". You like the idea of someone wanting you, it boosts your self esteem, and when you see him talking to other girls, you know that his infatuation with you will fade and you won't have that boost anymore. Don't let him know of your jealousy otherwise you will give him the wrong impression and that isn't fair. Just try and focus on something else to boost your confidence!

You get jealous because you like the attention. I'm the same exact way. Him liking you boosts your confidence, and makes you feel really important in his life. So when he flirts you loose that boost and feeling. To stop it you just need to realize that you don't need him to boost your confidence, that you're pretty already. And that he doesn't mean anything to you and your life when everything's said and done.
