I don’t think we feel only one thing in our lives. I don’t think it’s as simple as either (a) being in love or (b) not being in love. I think our feelings for each other are really complicated and motivated by an endless interconnected web of desires and fears.
You spend your whole life stuck in the labyrinth, thinking about how you’ll escape it one day, and how awesome it will be, and imagining that future keeps you going, but you never do it. You just use the future to escape the present.
