“There’s this idea in psychoanalysis that I’ve always liked.” Julian pulled himself closer and rested his head in the crook of Paul’s arm. “It’s that what we call ‘love’ is actually letting your identity fill in around the shape of the other person—you love someone by defining yourself against them. It says loss hurts because there’s nothing holding that part of you in place anymore. But your outline still holds, and it keeps holding. The thing you shaped yourself into by loving them, you never stop being that. The marks are permanent, so the idea of the person you loved is permanent, too.”
