Pesikta d'Rav Kahana 22:2

In Sidon it happened that a man took a wife with whom he lived for ten years and she bore him no children. They came to R. Simeon bar Yohai to be divorced, and the man said to his wife: “Take any precious object I have in my house—take it and go back to your father’s house.” Thereupon, R. Simeon bar Yohai said: “Just as you were wed with food and drink [being served], so you must separate with food and drink [being served].” What did the wife do? She prepared a great feast, gave her husband too much to drink [so that he fell asleep], then she hinted to her maidservants saying, “Take him to my father’s house.” At midnight he woke up from his sleep and asked, “Where am I?” She replied, “Did you not say, ‘Whatever precious object I have in my house—take it and go back to your father’s house?’ I have no object more precious than you.” When Simeon bar Yohai heard what the wife had done, he prayed on the couple’s behalf, and they were brought to heaven's attention (and given a child.)
