That exH had an affair about 5 years into our 15-year marriage (don't know how long it went on for) and that he was seeing his now partner before we even talked about splitting up. Maybe others too but not certain of them.
Our marriage broke down and we separated and divorced amicably in 2016. For the last 6 years we have been on great terms which has been brilliant for our 3 dc. I still held him in high regard because he's the kid's dad and I also got on well with his new partner.
I don't know what to do with this new knowledge.
I now feel like our marriage was just an absolute lie for the most part, but also the last 6 years has been based on lies too. He and his girlfriend must have been feeling so smug that I didn't make life difficult for them because they did such a good job in keeping it quiet, and he must be absolutely over the moon with himself that he kept the earlier affair/s secret enough to not ever have to take responsibility. The narrative of my life for the last 17 years has all of a sudden changed and I am SO angry that he has made a mockery of me for so long. 17 years. All that time wasted.
And I don't know what to do with my anger :(
