I know this is old, but hopefully this reply can used as future reference for any confused teenager... there is always one or 3 around! This is something I'll probably tell my own teenager daughter if I ever have one: I don't recommend you to have a relationship right now, you are so young and at your age you don't even know what you feel, let alone know for sure what intentions others have. It's a dangerous time!
Take your time, you will mature soon enough and will know for sure what you really want and like, specially when it comes to men. Girls who don't think this thru often end up screwing up and having teen pregnancies. Yes, you can be in love at almost any age, but is rare in a teen, most of the time what you think is love is actually ''infatuation'', which is a very similar emotion! And even if there is love... you might not be able to truly know for sure.
When you are a teen you don't see things like most adults do, can't really see the true danger of things, just glimpses and this is why we see a lot teen pregnancies or other awful things. This is simple because the brain of a teen isn't fully developed... until said teen becomes an adult.
This was just an advice for the girls out there, if you girls still feel like having a relationship... well, talk about it with your mom. Ask the guy to go for dinner, so your mom and dad can get to know him, your mom will surely know what kind of person this kid is by just talking with him that one time, would be better if you do that often... Trust her judgement, she CAN see things you just CAN'T and won't until you are her age.
