This Whole Relationship Thing

So, this blog is about relationships, and my lack of knowledge on the subject...

I'm 20 years old, currently a sophomore in college, and I've been with my girlfriend for about 9 months now, and I'm wondering if I understand what I have gotten myself into (and am continuously getting myself further and further into everyday that goes by).

Now, what I mean by this is that, hey I'm in school, shouldn't I be living these years like they really are the best of my life? I say this trying hard not to sound like a sleazebag, if that's possible, I dont know.

I do like her, my girlfriend, there's no denying that. I'm just in a mindset that maybe I've locked myself into this relationship at the wrong time.

So what I'm asking of anyone who may read this is some advice on the subject at hand that may let me sleep a little easier.
