Am I being shallow by wanting a smarter guy?

No you aren't shallow at all. If you settled for a guy who wasn't really up to you intellectually, wouldn't you be looking elsewhere all the time? You're honest with your feelings, a good trait. I like the more intellectual women too and usually have to look for older women. Not that much older, ten years usually does it. The girl I live with is great, but that's the one area she falls short in.
