You assume it was Rush. It is reasonable to consider that SHE may have had the affair. Perhaps marta was responsible for hiring the maid. Perhaps Marta got rush into this entire mess with drug dealing extortion. (how difficult is it for a wife to "place" a few damaging emails as insurance or worse.)
Could Rush have been covering for Marta, men do have a tendency to cover for a wife. Up to a point, at least.
You're insane.
