Selfishness can sometimes disguise itself as love. Infatuation and lust are manifestations of selfishness that disguise themselves as love. They are selfish, because they desire to use and to possess.
Love doesn’t wish to possess. Love sets free. Love sees others as children of God. Love wants to be loved back through free choice. Love is even willing to die on behalf of the beloved. Love desires spiritual companionship, not mere physical gratification.
