1992,13th April, Nelson Mandela separated from his second wife,Winnie.Since being freed from prison in 1990, Mandela testified, he had felt nothing but "loneliness" living with Mrs. Mandela, who once was hailed as the "Mother of the Nation."Their marriage had dissolved, he said, and he became convinced of her infidelity after seeing love letters from Mrs. Mandela to her personal assistant, Dali Mpofu.
I think this was a big day in Mandela's life because Winnie was with him for such along period of time and most people probably thought they would grow old together. It was probably very sad for Mandela but I think it was better for him, if they weren't happy together anymore than there is no point in staying together.
