"Love is selfless.

Love that is conditional, or transactional, is not love.

Anakin's "love" for Padmé was possessive and selfish. It was not love.

Padmé's love for Anakin was selfless. Seeing him become possessive, and selfish, and greedy for power broke her heart."

"This was the basis for Anakin's relationships—the death of his mother, and being unable to accept that, led to his fear for the death of Padmé, and his subsequent actions led to the dark side. That is his lonely place."
