Like Bttrfly posted, I'm writing this post with a soft tone to an online friend I admire
I think it would be a good idea to work on two areas in your communications with your XW:
Drop the emotion from your replies and aim purely for 'pleasant & businessy' (I think your responses to her still sound pretty reactive....which I understand & goodness knows how well I would cope if I had to be in contact with XH.)
Let go of the need to keep telling her that she is 'wrong.' She decided what she did and is where she is. I agree that it is up to her and your girls if they want to reconnect at some point and doesn't need for you to stand in the middle - only not stand in the way....
All JMHO of course and I too ache for your girls - and for your XW in fact. She has made choices that have led to great losses for her and I don't think she has the tools and resources to get her life back on a healthier track at this point.
As you know, me and XH don't have any contact. But if we did, I would try and operate/interact in a way that (if he died or killed himself tomorrow) I wouldn't regret my own interactions with him.
Take care Irish and I hope you relax and enjoy the weekend :)xx

We receive & we lose, and must try to achieve gratitude & embrace with whole hearts whatever of life that remains after the losses - Dubus
