I have NC for this. About a year ago I found out my DP was having an affair. We both agreed to go to counselling and to address the underlying issues and after 6 months plus hard work we came out it much stronger. I have recently had reason to believe that in the few weeks following the discovery of the affair whilst there was much tension in the air that my DP continued the affair before it was broken off. I am happy now and don't know whether to broach this now?
