The Feelings reading answers exactly one question: what is going on inside another person with regard to you. It suits the case where there are no words, or where you don't believe the words: he goes quiet, he stalls, he behaves inconsistently.
It doesn't show the future of the couple and doesn't answer "will we be together" — only the current state. And it is useless when you already know the answer and are looking for the cards' permission to disbelieve your own eyes.
