Richelle E. Goodrich said this quote

At the core of love is validation. It is what gives love power. For when love is given away, validation seeps in and expands in the heart of the recipient, filling up every empty, dark corner. It is a wonderful, light, consuming feeling we long for, and once found, we hope—even expect—it will forever remain. But there are times when that most precious love is revoked, and a hard scab forms over the empty hole. Though this scab is both healing and protective, it is the reason why validation from future love may not seep in so easily, no matter how wanting the heart.
