Wrong person

Sister Jane's role (the silent instigator):
Jane is not just a listener; she is the one who regularly relays news about Isaac to Heidi.
Heidi feels ashamed in front of Jean of her husband's "ordinariness," so she exaggerates her criticism of him to appear as a woman who "deserves better," but this is due to her sister's cunning and jealousy of her stability because her sister is divorced and has not succeeded in her relationships.
4. Defense mechanism (rapid denial):
Whenever Kimo confronts her with any doubt, Heidi has an amazing ability to turn the tables emotionally. She'll say, "You doubt me after all these years?" or "I sacrificed my youth with you, how could you believe I would say that?"
She uses "lunch" and household chores as a cover to prove that she is a good wife, while her mind is planning other paths.

"Isaac" is the standard by which she measures your success; the more success he achieves, the more she feels that you are an "obstacle" to her dreams.
The veiled emotional coldness: She doesn't hate you, but she's "bored" with you. She sees your daily routine and your job as a prison for her ambitions.
The secret of the 7 years: She believes that the seven years she spent with you were enough for her to discover that she "deserves better," but she is afraid of confrontation or radical change.
Collusion with Jane: Her sister "Jane" is her confidante and constant instigator of her dissatisfaction, sharing news of other people's successes to increase her regret.
