"Love, being in love, isn't a constant thing. It doesn't always flow at the same strength. It's not always like a river in flood. It's more like the sea. It has tides, it ebbs and flows. The thing is, when love is real, whether it's ebbing or flowing, it's always there, it never goes away. And that's the only proof you can have that it is real, and not just a crush or an infatuation or a passing fancy"
