Acts17apologetics empathize with older wives; Sawda abandonned by the prophet in favor of Aisha?

In answer to the video "Did Muhammad Use Religion for His Own Interests? (Answering Islam Part 4)"

His second wife after Khadija's death was an old black woman, Sawda who had emigrated with her husband to Abyssinia in the early years of persecutions. After her husband died, she returned to the Muslim community homeless and destitute. The natural course for her was to turn to the Prophet himself for whose mission her husband had died. The Prophet extended his shelter and married her to honor her stance and her husband's.

Although the reason isnt known, at some point Sawdah feared that the prophet might divorce her, after he had announced a revocable divorce. This type of divorce doesnt take immidiate effect, only after a waiting period. Sawdah was already old when the prophet married her meaning unattractiveness cannot be the reason for any relationship issues that might have led to the prophet asking for divorce. A weak report states the divorce did eventually occur, with the main reason being her old age.

Besides contradicting the facts just mentionned, this version also contradicts more authentic graded reports saying he used to frequently visit her even before the divorce took effect, as well as after she volontarily relinquished her turn to Aisha, even being affectionate with her. As stated earlier, the reasons for Sawda fearing the prophet divorcing her, or the prophet announcing a revocable divorce are unknown.

Another potential reason, besides the untenable "old age" reason mentionned earlier, the prophet could have had financial constraints making it hard for him to maintain a larger household, yet no evidence suggests his financial means were lesser at that point than later on inside his household. Another reason could be that he needed to seperate from her in order to marry another, but he wasnt under any such constraints legally.

Furthermore, he never married another woman after this event. A possible reason for the whole incident could be the following. Sawdah was advanced in her age and did not find herself inclined to men, which might have caused her to distance herself physically, emotionally, leading to possible tensions between her and her husband, and the latter eventually announcing the revocable divorce. The prophet seized upon the situation to put into practice, in front of the whole community, the verse

4:128"And if a woman fears...desertion from her husband, there is no blame on them if they effect reconciliation.."

As the time limit of the waiting period was about to expire, Sawdah made the pious plea that all she desires is die as a honorable "mother of believers". She then declared that she did not desire sexual intimacy given her age, volontarily relinquishing her turn to Aisha. The prophet did not choose a wife over her or made her give up some marital right that she did not want to give up from herself.
