one thing (looks) to get together.

Example: I met an attractive yoga instructor through my job. She was a gym rat and was in great shape. I was in great shape because of mountain biking, soccer and mountain climbing, but had never stepped in a gym to work out. I was attracted to her physically, but wasn't attracted to her in regards to wanting to have a relationship, even though she was very interested. Why? because she wasn't similar enough to me in other aspect of life (focused more on looks, fashion and working out). Well, later she met, dated and married a guy far more 'attractive' than me (a couple inches taller, more muscular... and also into working out)–in other words, much more like her. Now, she and I may have worked out, but we weren't 'similar' enough for me to be interested.
