Bob was unfaithful to Lisa. He did it because he said he was bored in the marriage, needed a change, and was acting out of character. While there was no doubt that he hurt Lisa, he was not driven by the desire to hurt her.
Lisa was unfaithful to Bob. She did it because she was hurt, vindictive, and intended for Bob to feel the intense pain of betrayal that she felt.
Did Lisa's plan work or did she simply embolden Bob to continue his affair since she was involved in one herself?
