Sorry DLS, but if you are suggesting that OIN spend time with attractive women in some desperate ploy to make his wife jealous I think that's not the best course of action... This would very likley trigger his wife to give up on the marriage entirely and frolic about herself...
OIN I think DBing is a LOT simpler to do when there isn't a third party attacking your marriage.
Once we can be SURE beyond a shadow of a doubt that the OM is GONE... from her workplace AND her imagination your wife will be a LOT more welcoming of reconcilliation if YOU are an inviting prospect
Her disrespect and dismissive attitude I think is largely thanks to the interference of OM... He's done a LOT of damage here... But he continues to do that until your WIFE is convinced he's gone and she gives up on him.
