What I hope you took from this conversation - and can use it as a reminder of you forget - is that what happened, and the end of your marriage and change to your family, really truly wasn’t about you or caused by you. You did your very best but, for whatever set of reasons, you were working one-handed. I suspect that matters to you and that it will matter to you in the future.
What I will sound a small parp-parp warning signal about is to beware others trying to pull you into any kind of triangles or roles that are not in your best interests. Those realisations your xh says he’s having - and they may or may not stick or translate into actions, time will tell - are imho no longer much your business. They may matter to him, or his mother even….but he is your xh now, not your h or partner. Right now, he is not even your friend bc there is little or no reciprocity. So maybe keep an eye on what feels appropriate or useful in your new role as an xw or even as a Co-parent? Just bc someone wants to talk does not imho mean you are obliged to listen. Things change when you are an xw surely? And that will probably get clearer with time.
But perhaps remind yourself that if supportive listening and your opinion made no real difference when he WAS your husband, it seems pretty unlikely that it will make much difference now. And it is perhaps rather selfish of him to think he should still be able to use you for support….particularly as I suspect he was completely unavailable to you in your own recovery process…..he is where he is bc of his own choices, he will either do the hard work on his own stuff as an adult or he won’t. Either way, beyond your control or responsibility, I’d humbly suggest? And his wanting to talk to you tbh might even be a return to an old pattern for both of you which no longer fits the realities of where you both are or keep you stuck in a role that no longer works for you.
Out of interest, what were you thinking when he said he wanted to talk to you? What do you think he was looking to get out of doing that? And you? What would have happened if you had said some polite version of No? Not suggesting this is some huge ‘fail’ on your part lol, just flagging it as something to keep an eye on maybe if it becomes a new pattern. (I suspect you might feel something about it linked to going he can be a better father? But that desire also creates a tender spot through which you can be manipulated, intentionally or otherwise, into playing a role in his psychodrama that may not serve you well. And tbh, is that a job, the build a grown up father task, you want to take on for the next 16 years? Jmo)
