it's just that I don't think they could ever really be friends because she would always want more
The whole "I love Dr. House" thing, while entertaining, was disappointing after she seemed to finally be over House. So you do, unfortunately, have a point. (And her scenes were House were actually cute this season! Please, TPTB, don't bring back creepy-obsessive!Cameron of S3.)

House/Wilson is so much more balanced, they both have a great affection for each other.
House and Wilson are like yin and yang. (Which reminds me of some other meta I wanted to write...)
