It sounds like the lawyers are doing their tactical moves on him. Maybe you have given your lawyer the impression that you do not wish to speak w/your h. It could be that his lawyer advised him not to contact you to discuss anything to do with the separation/divorce. They tend to do that.

If your daughter is comfortable in going over there w/the ow's sons there, then there shouldn't be a problem. I hope that I'm wrong, but I do think your h wouldn't be foolish enough to have her there after promising he wouldn't.

I will keep you and your family in my thoughts today.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
