Platonic affection?

No, Zoe thought, gritting her teeth. The flow of her anger seemed to dislodge something inside her, a realization. She wasn't physically attracted to Robert, but when he played with her hair and gave her backrubs, she felt sexy. Tonight was not a sudden revelation of Robert's true feelings, or even a confirmation of her sneaking suspicions. Deep down, she always knew for a fact he was attracted to her, because she went out of her way to make him feel that way. What she did realize tonight was that she had been using Robert for their whole friendship to make herself feel loved.

She felt like a tease—a whore.
