I stumbled across this while doing a bit of research on reciprocity, causality and disappointment. I found it to be quite fitting and decided to share it with you, my beloved readers.

"Not expecting something from something, or accepting that someone behaves incongruent with your values; is not equal to staying at the receiving end of it. I.E "I accept he will always find his needs more important than our collective needs. I don't expect him to change. I want someone who values our needs equally. Therefore, I will move along as I know, and accept that is the way he is; and it is something else I want."
