This person that she loves surprises her by persuading her away from loving them. It seems like the relationship might be a bit more struggling than the current situation the song presents, through "you talk me out of everything." All the same, she loves this person, would do anything for this person, even if it means falling out of (or at least, pretending to) love with them. And at the end, she thinks it might be okay. Love sacrificed for love.
