personally i would expose the affair. i have already done so in my stich. Even if he says that because you exposed the affair that now there is no chance- well at this moment there is no chance for you two to work on your marriage while a third person is in it. do not make it easy for him or for the ow. contact to other woman's husband. they caused this pain and should bear the conquses of their actions. my wife left me and hade an affair in 08 to 12 in 2008 she was put in jail. he went back to his wife december 2008 moved back in with me and the kids but kept contact with other man i had a problem with it she moved out sept 2009 been moved out on her own to current date still in contact with other man currently back in jail. a few months ago she left her phone here i checked it found the number--called other man left him message. it seems his wife was aware he and my wife were still cheating she recently wrote me a letter to say she is divorcing him i go to see my wife in jail on sunday
