Date Proposal?

On Wednesday, a woman that I've been chatting with online, asked if I was comfortable to have dinner with her. Without thinking much, I said sure, but I regret it now. I guess the major deterring factor is that her looks aren't that good. I don't want to sound shallow here, but I saw her Twitter pictures and I just can't stand her long finger nails and weird smile. I try to tell myself that the reason I'm not seeing her is because I don't want to hurt her feelings by only seeing her once. But who am I trying to fool? I know the main reason is because I don't want to see her, and gag as a result. I know I may sound shallow here, but what human can survive without breathing?

Is Physical Attraction Important?

I finally saw some additional photos of the online girl and discovered that her looks aren't what I originally expected. I don't want to seem shallow, but shouldn't there be at least some physical attraction if I am to progress further? Or are all women the same and that the only determining factor for their looks is their skill with makeup? Part of me tells me to continue trying to date her in order to gain experience and confidence with women. But the other part of me tells me not to hurt her anymore than I already have. I stood her up once and argued with her thrice. I don't think a future inevitable breakup will do her any good. I'm not saying that I'll abandon all future contact with her. I'll continue having her as a good friend, it's just that the feeling might not be there anymore.
