I asked ʿAisha about the option: She said, "The Prophet ﷺ gave us the option. Do you think that option was considered as a divorce?" I said, "It matters little to me if I give my wife the option once or a hundred times after she has chosen me."  

خَيَّرَنَا النَّبِيُّ ﷺ أَفَكَانَ طَلاَقًا قَالَ مَسْرُوقٌ لاَ أُبَالِي أَخَيَّرْتُهَا وَاحِدَةً أَوْ مِائَةً بَعْدَ أَنْ تَخْتَارَنِي  

I do not mind if I give option to my wife (to get divorce) once, hundred times, or thousand times after (knowing it) that she has chosen me (and would never seek divorce). I asked 'A'isha (Allah be pleased with her) (about it) and she said: Messenger of Allah ﷺ gave us the option, but did it imply divorce? (It was in fact not a divorce; it is effective when women actually avail themselves of it.) (Using translation from Muslim 1477b)   

أُبَالِي خَيَّرْتُ امْرَأَتِي وَاحِدَةً أَوْ مِائَةً أَوْ أَلْفًا بَعْدَ أَنْ تَخْتَارَنِي وَلَقَدْ سَأَلْتُ عَائِشَةَ ؓ فَقَالَتْ خَيَّرَنَا رَسُولُ اللهِ ﷺ أَفَكَانَ طَلَاقًا؟
