Teen dating is it a problem?

Alot of people start dating once they go into high school right? But can we really say that we are ready for a relastionship at this age. I can not tell you how many teens I have met that begin dating and within two weeks they start saying " I love you" to one another. And when thier relastionship ends they get hurt and make a big deal out of things. Some take it well others dont and it affects them in and out of school. Sometimes when your in a relastionship it distracts your during school. I know its happened to me. But it annoys me to think that some teens think that now that they have either a boyfriend or girlfriend they make their world revlove around that one person, whether you " love" them or not.
