She ends up doing the very thing which she hates in her husband. Adultery. Both are cut from the same cloth, spiteful and full of vengeance. No character development till the end. Toxic relationships. The married couples' world is shown in a cynical way. Too much of wasted, negative emotions are being invested in a relationship. Husband | wife cheat? Can't forgive? Okay say TA TA , BYE BYE! LEAVE! GET OVER ! AND MOVE ON with your life. LIVE AND LET LIVE. life is too short to hold grudges. Revenge , grudge is a toxic , wasted energy. She ruins him the first time, fine! Totally Justified.
Ruining him for the second time is pure EVIL. She is the real villain here. Totally disappointed the way how a successful doctors character is written in such a lowly manner. She couldn't let go, that is not love. That is obsession.
She was just a bitter, spiteful, arrogant, evil, cold hearted, rigid, unyielding lonely woman. Both of them are messed up. No wonder the son gets messed up too. I can't imagine what the writer was thinking when he penned down the storyline without any character development? What was the message in the story?
