When adult Jean is resurrected, adult Scott is already dead.
During her resurrection story, the Phoenix Force, trying to tempt her to accept it back, resurrects Scott. He tries to tell her he's sorry, but she doesn't let him finish. They hug, kiss and tell each other they miss and love each other. They talk very briefly. Then, when it becomes obvious that Jean won’t accept the Phoenix back, it kills Scott again.
During his resurrection story, he’s shown eager/desperate to go talk to Jean, but Kid Cable is keeping him in one of his safehouses and Scott’s only allowed to go outside at the moment Jean and the other X-Men are being taken to the Age of X-Man. So they never get to meet again at the point.
They only meet again at the very last issue of Rosenberg’s run, where they are shown being very much into each other and not interested in Emma or Logan at all. And after that, we’re already at Krakoa.
So pre-Krakoa, they never really have a chance to talk about their marriage. Really.
EDIT: Now, post-Krakoa, like everything else about this island, motivations and feelings are being kept vague. Personally, I think they're all being made to feel happy and that has its own consequences. But it's just speculation of my part.
