Which Puranas describe Tulasi vivah, celebrated in Shukla Dwadashi of Kartika.
Vishnu tricking Tulasi was discussed in this answer. But looking for references where Vishnu married Tulasi.
"Tulasī quitted her mortal coil and assumed a divine form, began to remain in the breast of Śrī Hari like Śrī Lakṣmī Devī. Hari also went with her to Vaikuṇṭha. Thus Lakṣmī, Sarasvatī, Gaṅgā, and Tulasī, all the four came so very dear to Hari and are recognised as Īśvarīs."
