Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 56


भ्रातुर्विरूपकरणं युधि निर्जितस्यप्रोद्वाहपर्वणि च तद्वधमक्षगोष्ठ्याम् ।दु:खं समुत्थमसहोऽस्मदयोगभीत्यानैवाब्रवी: किमपि तेन वयं जितास्ते ॥ ५६ ॥


bhrātur virūpa-karaṇaṁ yudhi nirjitasyaprodvāha-parvaṇi ca tad-vadham akṣa-goṣṭhyāmduḥkhaṁ samuttham asaho ’smad-ayoga-bhītyānaivābravīḥ kim api tena vayaṁ jitās te


When your brother, who had been defeated in battle and then disfigured, was later killed during a gambling match on Aniruddha’s wedding day, you felt unbearable grief, yet out of fear of losing Me you spoke not a word. By this silence you have conquered Me.


Here Lord Kṛṣṇa refers to an event that will be described in the next chapter. Thus Kṛṣṇa’s talks with Rukmiṇī must have taken place after the marriage of Aniruddha.
