As I posted before, it's just all so very tricky for outsiders to judge whether or not another couple has "true love".
By every account, JFK married Jacqueline Bouvier in 1953 because she was intelligent, Catholic, beautiful and "classy". His ambitious father Ambassador Kennedy is said to have engineered the marriage so that his son would have a presentable spouse when he achieved the White House.
Jacqueline was raised to marry into what her social climbing mother called "big money".
In other words even though the couple was physically attracted to and appreciated one another, neither of them was said to have married primarily for love.
JFK's affairs during the marriage are the stuff of legend, several of his biographers believe he suffered from a sexual addiction.
But after reading first hand accounts of the marriage from people who knew them well I am more than convinced that they loved one another deeply in their own way. For Jackie in particular this brilliant, handsome, profoundly flawed man was the love of her life. His assassination reportedly drove her to contemplate suicide.
She told one of her maids that as he lay dying in her arms in the Dallas motorcade she kept telling him that she loved him, because she had read that dying people can still hear and she wanted that to be the last thing he heard in this life.
You can just never know what really goes on in someone's marriage.
