itaḥ svayam apasṛtya tatra sthita upajapaṃs tarkayitavyaḥ//

(4) In the case of the man who may have left the one woman of his own accord, and be living with another woman, the former (wishing to take up with him again), should first ascertain if he left her in the first instance in the hope of finding some particular excellence in the other woman, and that not having found any such excellence, he was willing to come back to her, and to give her much money on account of his conduct, and on account of his affection still existing for her.
