I guess you're seeing a different "try" from her than I am. I see a wayward wife still apparently in contact with OM, and as long as she's getting at least SOME "fix" from that drug, she's never going to be emotionally available to her husband.
I also think it's damned near impossible for true reconcilation to happen on a foundation of deceit. Unless and until the two spouses can be fully honest with each other, how can they possibly begin to do the difficult work of reconciliation? Reconciliation in cases where infidelity was involved require different types of work, no?
