What is your advice to a married man with children who has fallen deeply in love with his wife's sister, despite his attempts to forget her and distance himself from her, and who wishes to marry her to be free from his love or to forget her?

The inquirer's condition can be treated by consistently engaging in the remembrance of Allah (dhikr), reciting the Quran, and supplicating (dua), as these are effective remedies. This is coupled with the certainty that a person can overcome their inner self if they seek Allah's help and earnestly and resolutely adopt the necessary means.
