Jokke has said, I think in the book for fred's birthday, that he pulled away from Fred because Fred was so happy getting married just as Jokke was feeling bitter about Alex and that they were just on different wavelengths. Fred was hurt that Jokke turned to his friends rather than his bro for support. According to Jokke they are now back on track.
Jane. Jokke's comment also makes me wonder when the wheels came off in the Mary-Fred relationship. Sorry Maria
(may be OTT).
I think it was a multi-layered thing.
When Joachim and Alex were married, Fred was always welcome, and they had a really nice friendship/family going. Fred was the CP, but Joachim and Alex were the defacto CP couple then. There was not as much attention on Fred. Work and private wise. He could bum around, chase girls, etc.
That changed when Joachim was in the process of divorced, and Fred played around with Mary...everything came to an end for Fred. Joachim's divorce was final, Fred knew he had to step up, take responsibility, marry, and slide in the role that Joachim had fulfilled for some time
Mary chased him down in Denmark via Paris, latched on like a tick, and is bleeding him dry ever since. Xtian was duty, so was Izzy, and the twins came about to secure "her" line the throne and to put as much distance as possible between the Derf's and the Schack's place to the throne.
