Does this make me a bad person?

A little while back I went out with this girl on a kind of "friends set you up" type thing. I guess you could call it a blind date. Yeah, it was a blind date. I didn't want to say it, but I guess, yeah, it was. Anyway, she was cute, friendly in a good way (as in not overanxiously friendly) and in pretty good shape, which helps. We had a nice dinner and talked for a bit at the coffee shop afterwards. Unfortunately, by the end of the evening it was apparent that we had no chemistry and we really didn't share any common interests. The date ended on the usual, "I had fun, thanks, see ya," type goodbye. A good time was had by all, but not that good a time. I'd say, "an okay time was had by all," but that just doesn't sound right. Regardless, it wasn't gonna work out.

Anyway, one of the people involved in the setup saw her at a party recently. It turns out she's put on quite a bit of weight since I went out with her. When I was told this, my brain's electrical impulses immediately went to the "relief" pattern. The only thing that went through my brain was, "Whew, I really dodged a bullet there!" Am I really that shallow? I mean, really. The girl was nice enough, and I doubt I was any sort of reason for her to go into a depressive cycle which caused her to gain tons of weight or anything, but I didn't feel bad for her at all. No sympathy, no empathy, no concern. I just thought about what a relief it was that I wasn't stuck dating her when she put on that weight as an automatic reaction. I still don't really care, other than how it affects my self-image.

It just makes me think that I really am as shallow as I joke to my friends about being. It's like every time I wonder if I'm too shallow, I answer my own question by scooping another bucket out of the pool. I guess I really am a bad person. That's alright, though, as long as it means I don't have an overweight girlfriend, right?
