What do you think Love is?

“You know what getting married is? It's agreeing to taking this person who right now is at the top of his form, full of hopes and ideas, feeling good, looking good, wildly interested in you because you're the same way, and sticking by him while he slowly disintegrates. And he does the same for you. You're his responsibility now and he's yours. If no one else will take care of him, you will. If everyone else rejects you, he won't. What do you think love is? Going to bed all the time?”
