Personally I'm of the belief that the emotional expectations some people get form fiction are worse than any of the physical ones. Boobs are boobs and you will be more physically attracted to people who you "fall in love with." But the emotional expectations of "soul mate" is mostly just an excuse not to try if thing's aren't perfect. Sometimes you and your partner will make mistakes you'll have to work though it. But in fiction it's "happily ever after."
