The WAS' are blind to parallels like that. My MiL cheated on her husband and then asked him for divorce, which wreaked havoc on my W, lead her to have a nervous breakdown when she was in college.
She cheated on me then asked me for divorce but was convinced that our kids would be fine. I asked her if she saw any parallel between her path and that of her mother and she said no, there was no similarity at all.
I wouldn't bring it up. Eventually he may see it, but even if he does it's unlikely he'll admit it. You bringing it up just pushes him away and you want to focus on things that draw him closer.
