Was her father angry or something? and how good was their relation before Justine met Pierre Yves?? Did Her Dad always by her side? Cheering 4 her in every tourney she played?
I am not sure about the 'angry' part, but he was by her side in the beginning of her career (when she won the Junior Championships at RG, and a couple of years after that). Anyway, if PY was really the reason why they "split", she was definitely right to go her own way ! This little slip of a woman does know what she wants (and how to grab it)
Of course the British tabloids squeezed her for info about her father the year she reached the finals at Wimbledon, but she sent them all packing (clever girl).
Maybe she talks about it in her new biography. If not, then let's just respect her need for privacy.
There must be something about all these dad's and their tennis playing daughters ....Graf , Pierce , Jennifer , Dokic.....all have had problems with their dad at one point in their career . Monica OTOH had a great relationship with her dad ! (even Jen and her dad seem OK these days )
