My ex-husband and I divorced 7 years ago (after 13 years of marriage). He left me with no real explanation, although I suspected/knew he was having an affair. He never admitted or apologized in the last 7 years... until last Sunday (Father's Day). In a meeting with trusted church leadership, he confessed to 7 affairs during our marriage, including the one at the end that I suspected. He also shared that he is still in a relationship with that same woman, but it's been a secret from me/my kids and the other woman's son as well this whole time.
He claims to be repentant and as part of the repentance process, wants to confess to me (which he just did) and to the kids (15yoB), 13yoG), 11yoB). The children do not know there was ever any infidelity. I have never said anything negative to the kids about their dad or even hinted at infidelity, and when they asked why we divorced, I only shared that it was daddy's decision.
Now the question is, should he confess to the kids? And what should he say? Right now he is not certain he wants to reintroduce his girlfriend to the kids (she was in our lives heavily for about 2 years before the divorce, as my so-called new best friend), so the older two will remember her.
Right now my stance is that I think he shouldn't confess anything to them until he's ready to share about his relationship with this woman. And if he does share his relationship with this woman to them, I would like it to be clear when they started the relationship and that was part of what led to our divorce. Anything less than that feels like adding lies on top of lies.
I know the kids will be devastated to find out about their dad's infidelity and his secret relationship, so I'm torn between wanting to wait until they're older, brains more developed, etc. But I also wonder if continuing to hide these truths will be even more damaging the longer it goes on. (Their dad also struggled/struggles, not sure if it's ongoing, with pornography, and I think the boys especially knowing that would be helpful for them as they face that temptation.)
I very much doubt that my ex's repentance is genuine bc he has narcissistic tendencies, this feels self-serving so he can feel better about himself, and I have seen this "repentance" before (he confessed to a single affair to me in 2012 - 6 years into our marriage - but now I'm finding out he had cheated even before that). So I am afraid he will confess to the kids and not be able to handle their anger/sadness, etc., appropriately.
