No, she really doesn't. We don't need details to know the fundamental fact that he cheated, claims he wants to stay married but continues to have contact with his affair partner. Knowing details won't alter any of those things or change the answer: Unless he goes no contact, forever, he does not truly mean it when he says he wants to salvage the marriage. He has to put in the work to salvage things, and THE key part of the work is completely going no contact.
If by "details" you mean something like, "But what if they're work colleagues and he has to at least interact with her someat work" or whatever-- OP surely would have said so if that were the case. And even if it is the case, well, cheating DH needs to find a new job or ask for a move within his current organization. If he put himself into a position of having to torch his career or having to stay in contact with an AP, well, that's on him. But again: We don't really need details.
