ppenton, sorry to see you here. Need to continue reading Divorce Remedy and Divorce busting. Another great book - suviving an affair by Hartley which is a bit more agressive than DR or DB.
Tell us more about the OM. Is he M or single? Have you exposed the A to her parents or if the OM is M to his wife? Nothing kills an A than having it exposed to the light.
Are you supporting her financially? If so -- stop it now. Is WS giving you child support?
You can still DB but make the Ws accountable for their actions. The C that your wife is using is not pro-marriage and sounds like a nightmare.
Work on yourself and concentrate on your kids.
