Hi Michelle,
Thanks for this support.

It was really timely because D16 and S14 were really rattled by something that happened in the car when their dad was picking them up from school yesterday.

The car has a phone system that displays caller name and broadcasts the call audio.

Yesterday was his birthday - so we were all on tenterhooks to see how to cope with it.

What happened was that the phone rang and a female name unknown to the kids popped on screen. He answered and a young girls' voice started to sing 'Happy birthday'.

He thanked her and asked about school etc. A young boy's voice could be heard in the background. H asked him about Minecraft ( a game that my son loves to play). It was obvious H has a pretty close relationship with these kids. My own kids were deeply hurt and upset by this. They don't know who these kids are - but they seem to have taken over their relationship with their dad.

I suspect they are OW's niece and nephew.

I'm tempted to speculate that H answered this call in front of them because D16 and S14 have shown their reluctance to go to H's new 'home' - OW's apartment - with H, and neither will they go out to dinner with him (where he wants to introduce them to OW).
He is very retaliatory - just like a 2-y-old.

I'm trying to pick up the pieces with them now. I appreciate your advice, and will tell them that it's Ok to feel hurt and angry.

This just gets too awful sometimes...
