Trying to put everyting I've read and seen on TV so far (I haven't seen the interview with Sybille yet, only bits and pieces in the news)
1959 Albert marries Paola. Philippe is born in 1960, Astrid in 1962, Laurent in 1963
1962 Sybille marries Jacques Boël
1966 Albert & Sybille start their relationship
1968 Delphine is born. Sybille is married to Jacques Boël so he is automatically the legal father.
Albert, Sybille and Delphine practically live together as a family in Brussels and at the Belgian coast.
1976 Albert wants to divorce Paola, Baudouin agrees, Sybille refuse to agree with the conditions the Palace demands.
1978 Sybille divorces from Jacques Boël
1982 Albert & Sybille's relationship ends, Sybille remarries and moves to London
1980's Albert and Paola get back together (some say they found each other again at Philippe's graduation party, other say it's around Astrids engagement)
1999 A biography of Paola reveals the existence of Delphine. And she is chased by the press. In his new year's speech at the end of 1999 Albert says 'that he and Paola were confronted with a difficult time in their marriage 30 years ago, that it is private and that he wishes not to comment on it
up until the end of 2000 Delphine receives gifts from Albert for her birthday and christmas, she calls the palace when the gifts stop coming (Sybille told this in an interview with TV show Royalty)
2003 Delphine moves to Belgium and regularly gets press attention with her art, especially the pieces in the colours of the Belgian flag or with clear references to Albert
2004 Delphine didn't want to talk about Albert for the past 5 years, but now she tells that she and Albert have no contact anymore with each other
2013 January Delphine says Jacques Boël did everything to keep her from inheriting from him by putting his fortune in foundations. After he dies (and when he's still his legal child) she could object to his will and claim her part.
2013 June Delphine goes to court and wants to prove her descendance with DNA from Philippe, Astrid and Jacques Boël
2013 July Albert abdicates
2013 September 3rd Delphine changes her case and only wants DNA from Albert (He can refuse a DNA test according the belgian law, confirmed by his lawyer)
That evening the first part of an interview with Sybille is aired. She agreed to be interviewed when it was put into a contract that the interview could not be aired before Albert's death or abdication. Apparently she wasn't expecting the abdication to happen during the interview session. Review from the first part of the interview (google translate)

So IMO both Albert and Sybille are equally 'guilty' of Delphine's situation.
After the affair ended and Paola and Albert get back together, Albert still sends gifts to Delphine but doesn't see her anymore. That's what sometimes happens with kids from divorced parents too.
He stops sending gifts around the time Delphine gets press attention. Because he's angry of her indescretion? I also think Delphine came to Belgium hoping to launch her carreer as an artist because she's famous now and that didn't turn out the way she wanted.
I think Albert should have handled the situation in 1999 by making a Mitterand-like 'et alors' statement and Delphine should have stayed in London. She could have been his known illegitimate but discreet daughter.
But now everybody is just bitter and angry at each other
Delphine and her mom at Albert for ignoring her
Albert at Delphine for being indiscreet
Jacques Boël for being dragged into this whole situation.
We'll see what happens next.
