As my thought, I think George wife cheated on him with tom because Tom is rich and he can fulfill her dream and getting her a house in west egg. George became sick because he somehow got to know that he was being cheated and needs money to make his wife happy to fulfill her dream, so that she comes back to her. Tom was jealous because of Gatsby and Daisy’s attitude and there freely conversation was making him so missed off that he went to the boiling point and creaked; but didn’t have any ridiculous action 2wards it except yell when he was talking. By seeing this reaction you can tell that cheating is easy but the person who is being cheated gets deeply affected in a way. George attitude was for love and getting her back with any means or motives; in the other hand Tom was ferocious because of jealousy and wealth competition. Tom’s wife Daisy cheats on him because of love passion and because of the extra ordinary past.
