Glad you had a turning point. I know he doesn't want to keep "picking at the wound" but you have to get the "poison" out so to speak. When my ex had his first affair he didn't want to talk about it and things in our lives were moving so quickly, I let it go or so I thought.
The betrayal came up in little ways over the years. I was so busy with the kids, it still never was discussed much. So it came back and bit us in the rear. So even though it is painful , get to the bottom of it. Just don't keep at it once you have your answers or neither of you will be able to heal.
