<human>: Hey reddit.

Background information:
I've been in a relationship with my SO for almost 4 years now (we began dating in high school), and I'm rather young (college). My SO is also in college, and we are currently 200+ miles apart. We are as happy as we were the day we met, and I can only recall having 2 arguments with her ever.

As this year at school is wrapping up for me, I am looking forward to returning home to my SO, and the same is for her. I honestly can't complain about anything in our relationship. The only issue we have ever had is religion, but we never fight about it and are both extremely understanding on the matter.

We've already discussed the idea of eventually getting married after school, and how religion would tie into this. Everything is peachy.

So where's the problem? The thing is, my SO is my first long-term (2+ years) serious relationship. The same goes for her. I am constantly wondering if I am taking the first thing given to me and missing out on something potentially better. There are traits in her that I wish were a different way, but they are mostly superficial, and none are major in any way. Nobody's perfect, right? I definitely have way more issues than her.

What should I do? Am I just afraid of commitment, or is this a legitimate concern?

Can you provide a brief overview of the text?
