Hi Lone77, I'm sorry your D had that experience. In a 'normal' scenario, parents would be able to be the adult in that situation. However, for MLCers the focus is on self and there's an attitude of - I need to do this to make ME happy, can't you get with the programme?
Anyone who challenges choices at this stage may become sidelined - including kids and close family. When you say he seems jealous of the R you have. Yes, perhaps that's the case. He wants to be able to do all the stuff he wants to do - and enjoy the bond like you and she has - and is perhaps frustrated that he can't.
As for moving in with OW - well, it can't be nice to hear that. However, closeness is perhaps no bad thing in these sitches - as I think it's hard for both the MLCer and OW to keep up 'good' behaviour and this can lead to the breakdown of the R sooner rather than later. I read once that R's which began as A's are built on foundations of sand which tends to get washed away in the storm...
Hope you manage to find a lovely dress for your D xx
