Hey WH, Melissa,
Thanks for your support on this.

Of course, i did not say a word to them about XH. I never do.

We had an OK time, but it was sad to be there and be reminded again of what we have lost.

S15 looked like he was about to cry most of the time...

I can't get over the feeling that by not talking about what XH has done, we are all enabling his egregious behaviour. I think his parents have done this all of his life.
And they are so insensitive:
Oh, NLW, we have just bought this terrific thermo cooker. It cost $2,500. You should get one - it'd be prefect for you to cook for the kids in one pot and so quickly.

And: Oh NLW does your mother still drive?

No, she had to give us her car.

Oh well, good thing, I suppose, at her age...

Like WTF?

But anyway, no longer my place to try to put the brakes on XH, nor is it my concern. And if his parents want to ignore what he's done to us... that's their prerogative too.

I got a tension headache from being there though - all that fake smiling, and trying to think of what to say next.

Anyway, I'll get over it, but hope i don't have to see them again soon. It's too painful. They seem only to want to wheel us out for 'festival ' days - Easter and Xmas, none of the hard day-to-day slog. Again, makes me mad but that's just who they are.
