I believe he did not treat Christina very well. That the family kept inviting the late duke of Parma to family events but banned Jorge Guillermo completely says enough. He was said to be unkind and with bad manners and with belittling remarks towards his wife, apparently witnissed by members of the royal family.
When Christina met Jorge he lived together with a man, Ned O'Gorman. He had studied Art History and worked at a kindergarten for socially underpriviliged children in Harlem, New York. After the marriage Prince Bernhard supposedly arranged a more respectable job for him at KLM and later at Golden Tullip Hotels. The latter let him leave the company with a small compensation. In the last years of his marriage he mainly focussed on buying art and old wine. He also wrote a few coffee tables books. one of them about Cuba, which experts claimed had little to do with the reality on the island. The art work was all auctioned off after the divorce.
After the divorce he studied History of Art and Theology at Leuven University in Belgium. He befriended a priest with the last name of Dobson. In 2005 it was claimed in the gossip press that they were more than just friends. Later he moved to London -where his daughter Juliana lived with him- and in 2005 to a small castle in Condome, France. From his divorce he did not gain much money as the couple was married with a prenuptial agreement.
