I think she's always been obsessed. Irina is good but SHE'S PUTTING RAMBALDI FIRST! SYD AND JACK ARE SUPOSSED TO BE FIRST!!!!!!!!!!!!
Unless she has to go after Rambaldi to serve and protect her family. As I've said, the only way I can see for her to have betrayed Jack and still love him is if that betrayal were necessary to protect him and/or Sydney. Otherwise, why would she not enlist his help? They work together so very well. This is part of the missing information--and were it to prove true, it would explain a good deal of her behavior.
However, look at what she's done in the service of her family! Jack would do these things himself (and has done some pretty difficult things) for Sydney, but he would never approve of Irina doing the things she has done for his sake. He would probably prevent her, even if it meant sacrificing his own life.
As I've said, the door is open for her, but any tangible information that says she's good is still missing. Hopefully, we'll get some more information before the season is out.
