If OP isn't satisfied with Larry, why doesn't she just divorce him? Or don't they have divorce by mutual consent, or because of incompatibility in this country?
I think she was happy, until Larry became withdrawn and cold. When investigating why he could be pulling away, she discovered that he had hired John to entrap her into an affair so that he could divorce her and walk away with $7 million. All she did was flip his plan around on him, to do to him what he had wanted to do to her.
