Tostada,
You have written a few times that you would like to give OM's wife the info. If you think this will help your case do it...I would caution however, that should the other man break up with his wife, he will be wide open to pursue yours. Maybe he just does not have the Bs to tell his wife.
Sorry about the papers...sorry about your health. Do what you think is right. You are in control. You are the one that wants to work through this.
Keep your chin up.
