Initiating divorce proceedings in May 1956, she claimed that Mandela had physically abused her; he denied the allegations, and fought for custody of their children.

After resigning from the RAF and traveling around the world for 18 months Townsend returned in March 1958; he and Margaret met several times, but could not avoid the press ("TOGETHER AGAIN") or royal disapproval. Townsend again left Britain to write a book about his trip; Barrymaine concluded in 1958 that "none of the fundamental obstacles to their marriage has been overcome-or shows any prospects of being overcome". Townsend said during a 1970 book tour that he and Margaret did not correspond and they had not seen each other since a "friendly" 1958 meeting, "just like I think a lot of people never see their old girlfriends". Their love letters are in the Royal Archives and will not be available until 100 years after Margaret's birth.
