“Some people are good at being in love. Some people are good at love. Two very different things, I think. Being in love is the romantic part—sex all the time, midday naps in the sheets, the jokes, the laughs, the fun, long conversations with no pauses, overwhelming separation anxiety … Just the best sides of both people, you know? But love begins when the excitement of being in love starts to fade: the stress of life sets in, the butterflies disappear, the sex becomes a chore, the tears, the sadness, the arguments, the cattiness … The worst parts of both people. But if you still want that person by your side through all of those things … that’s when you know—that’s when you know you’re good at love.”
