Did a divorce occur between the spouses after the second pronouncement of divorce uttered by the husband via the internet, and is the wife obligated to return to her husband if he wishes so, and is she considered disobedient (nashiz) if she does not return to him, and what should she do to free herself from this marriage?

The second divorce (talaq) pronounced by the husband online is considered binding if the wife ascertains the speaker's identity or if the husband intended divorce by writing. It is a revocable divorce (talaq raj'i) if it occurs within the 'iddah (waiting period). The phrase "You are divorced forever" (أنت طالق إلى الأبد) signifies an irrevocable divorce (baynunah kubra) according to the majority of scholars, but it is counted as a single divorce. The husband's statement "I do not want a divorce" is insufficient for revoking the divorce; he must explicitly pronounce the revocation. Reconciliation (raj'ah) does not require a face-to-face encounter, but it is recommended to have witnesses, especially if the wife is absent. If the husband revokes the divorce during the 'iddah, the wife is not permitted to seek a divorce except for a legitimate Shar'i reason, such as the husband's prolonged absence.
