No! Everyone has expectations!
It doesn't matter if you are buying a product or exchanging vows you expect that what you are being given will live up to (it's "promise").
Most people "expect" relationships to consist of Honesty, Trust,
Loyalty, Love & Devotion, Intimacy, and Emotional Security.
Not many people would want to enter into any relationship without most if not all of the above traits. Imagine someone saying to you, "I promise you nothing! Don't expect anything from me! I bring nothing to table and I'm here for me only!"
Odds are they aren't going to have too many friends.
In fact we "expect" strangers to be polite! (not rude)
Early on in life we're taught how to "behave"
There is nothing wrong with having expectations as long as they are leveled at someone who has made a promise, assured us, offered a guarantee or pledge to us. It's only natural to "expect" honesty in any type of relationship.
