Even though I know we're not supposed to bring this up, in conversations I have brought up the long-term consequences of divorce; I've lived it -- my parents split (quite acrimoniously) when I was 18. It was a horrible situation, my father was a violent alcoholic and my mother had been having an affair for years, but despite all that the divorce STILL was awful, still was the worse alternative , and the ramifications continue 30+ years on.
Slight caveat here: I do believe that sometimes an addict (which an alcoholic is) needs to be left. And in this case if my mother hadn't left my father may have well died, and her leaving was the catalyst to his working on recovery. However my mother herself said that she probably wouldn't have gone if she didn't have someone else, and while I know how my father belittled her and I understand how awful she felt I'm still angry that she chose to have the affair.
My mother married her affair partner and is happy, although her H has never been really involved with our family -- he wants her to himself. I will admit that I've never liked him; I "accept" him as a fact of life.
My father remarried as well, to a woman I have a lot of time for, she IS involved with our family (easier, as she wasn't the one who broke anything up), but all in all it is still a horrible mess. It goes down the generations, and the scars on my siblings and me are huge.
And this is despite everyone "getting along on the surface". No parent has disappeared, financial obligations have been met, all that.
Anyway, the times it has come up with H and I've asked (I know, I know, no questions) if he's read anything about it or thought about effects on children long-term he says that no, he hasn't.
I know telling him about it or worse, sending him written material, is NOT the thing to do, so other than what's already been said I refrain.
I'm glad to see that this gets some print space; I would of course like to see it be a lot more in the forefront, as would we all.
