Gittin 73B

כאשת איש לכל דבריה. רבי יוסי אומר: מגורשת ואינה מגורשת.

like a married woman with regard to all of her matters, and she remains forbidden to other men. R' Yosei says: It is uncertain whether she is divorced or whether she is not divorced.

גמ׳ תנו רבנן: ראוה שנתייחדה עמו באפילה, או שישנה עמו תחת מרגלות המטה ⁠– אין חוששין שמא נתעסקו בדבר אחר; וחוששין משום זנות ואין חוששין משום קדושין. רבי יוסי ברבי יהודה אומר: אף חוששין משום קידושין.

Talmud: A baraita states (Tosefta 7:4): If, after the giving of this bill of divorce witnesses saw that she secluded herself with her husband in the dark, or that she slept with him under the foot of the bed, one is not concerned that perhaps they were engaged in another matter, i.e., sex. And one is concerned due to their action of licentiousness but one is not concerned that due to their actions they performed a betrothal. R' Yosei, son of R' Yehuda, says: One is also concerned that due to their actions they performed a betrothal.

מאי קאמר? אמר רב נחמן אמר רבה בר אבוה, הכי קאמר: ראוה שנבעלה ⁠– חוששין משום קידושין. נתן לה כספים ⁠– חוששין משום זנות, דאמרינן: באתננה נתן לה; ואין חוששין משום קידושין. רבי יוסי ברבי יהודה אומר: אף בזו חוששין משום קידושין.

The Talmud asks: What is the baraita saying? Rav Naḥman said that Rabba bar Avuh said: This is what the baraita is saying: If they saw that she had sex with her husband, then there one is concerned that due to their actions there was a betrothal and perhaps through this act he intended to remarry her. If he gave her money immediately following the sex one is concerned due to licentiousness, wherein we say: He gave this money as hire for a prostitute, but one is not concerned that due to their actions they performed a betrothal. R' Yosei, son of R' Yehuda, says: Even in this case one is concerned that due to their actions they performed a betrothal, i.e., one is concerned that he gave her the money as betrothal.
