What's the point of a girlfriend?

Relationships are an important part of adult life, so dating as a teenager is just a chance to learn and practice. Having a successful relationship actually requires a certain amount of skill. On the other hand, it is by no means crucial or even necessary to have a relationship as a teenager, you can learn about relationships in your twenties. It sounds to me like you've got a good head on your shoulders and you are focusing on yourself. An important part of being in a relationship is feeling whole as a person, and having your own life, it sounds as if you're headed on that track. Its kind of six of one half a dozen of the other, though you're setting yourself up nicely for independence which is great. People just have different approaches to life, neither is really better than the other it just depends on what suits you!
