Thanks for the additional links, Cherries!
Rhinestone, thanks for clarifying about DD's apology. I get ES' wanting to talk w/ her and see that as a positive. However, IDKY he didn't just ask her to meet instead of asking her to ask him, etc. That sounds like stalling to me. It also sounds like he's trying to put her through her paces, to use an old expression. Did she agree to meet w/ him? If so, do you know how their talk went?
I'm sorry you're caught in the middle and think you should extricate yourself if you can. Let them both know they have to work it our on their own - or not, as they choose. If they don't resovle this and, as a result, ES continues to be ES, that will be sad. But your trying to help isn't helping, anyhow, unfortunately. IMO, you might as well save your energy and strength.

Soops kitchen, a place of reflection, refuge and at times revelry.
Retiring and living frugally in money from downsizing after years of stress
Even though I'm trying to ignore!
