Talmud zu Nedarim 10:8

HALAKHAH: If she is permitted, he is permitted³⁵This now refers to the first sentence in Mishnah 2 and explains why his vow disappears with hers. The explanation is that given by Abbai in the Babli, 22b.. If he is permitted, she is not permitted³⁶Since her vow was an independent act.. Rebbi Abbahu in the name of Rebbi Joḥanan: Because he makes his vow conditional on hers, if he says, on condition that you [accept]³⁷But if the Mishnah is taken as formulated, that the husband’s vow is absolute and the wife is only invited to participate, if she has her vow revoked by an Elder, his vow is not touched..
