<human>: I have been really good friends with a girl for a few years now who I am very fond of. We went to the same high school together, and hung out for a few summers in a row in between college semesters. I have a lot of respect for her, and always really enjoy our time together. 

We do crazy stuff together like bungie jump and spontaneously travel. We have tons in common, like the sports we play and the things we enjoy doing, and both want to be teachers. 

This is the part where I will probably come off sounding like an asshole. But, I figure full disclosure is best to get good advice. The problem is, I don't find her super attractive. I would definitely consider her to be pretty. But even my friends agree that everyone I have dated in the past has been much better looking.

I don't see that as a deal breaker at the moment. But, I am nervous that if I get into a long-term relationship with her and even possibly marriage, I might not find myself as physically attracted to her in the future. So, I guess it comes down to looks vs. personality. Is one better than the other or do you need a mix of both?

What are your thoughts? I know that she likes me, and would be willing to start a relationship. I don't want to have a relationship with her and risk losing the friendship if I end up not finding her attractive soon after. I appreciate anyone's answers.

Can you condense the text into a few key points?
