Fortunately, there are two reliable signs that love is not genuine: disappointment and anger. Every time we frown, sigh with disappointment, speak harshly, or in any way express our anger at other people, we’re communicating that we’re not getting what we want. At least in that moment, we are not caring for our partner’s happiness, but only for our own. Our partner then senses our selfishness and feels disconnected from us and alone, no matter what we say or do.
