Why doesnt she love me?

At 13 your brain is technically not ready for all the thoughts and feelings a relationship brings. Im not saying your immature, Im saying both of you are too young. Its great to be friends and its ok to flirt but there is plenty of time for you to be in love. Enjoy being 13 and having fun. Love is a very serious and deep word that can hurt both parties involved very much. To be in love with someone (in my opinion) first off you are the best of friends, you know everything about each other, can talk to each other about everything, TRUST is a major link, most of all thinking about each other when your not together, like feeling like a part of you is missing when the other one is not around. The biggest thing here is the feeling has to be mutual. But right now both of you are too young to be in love. Now is the time to concentrate on being friends having fun and doing good in school. There will be plently of loves in your life, the earlier you start the faster you get hurt. Just be a kid while you can.
