DO you have any physical evidence about your W's A with the om? If yes, the om will stop if you show him the evidence. Such politician is coward. They only think more about their reputation than really committed to a R, especially an A. Of course you should not make it public if you want to protect your W's reputation. It is just a treat for the om to back off. Just a suggestion.
Remove the om does not mean it will resolve your R problem. It only makes it easier without a third party in the middle. To D is very bad for everybody financially. That's why DBing can save you a lot. It also good for your family in the long run. Hope your W can see that and wake up.
