Feeling Sad....d12 with exhnarc, OW skank and her daughters for big 'family' getaway

I'm struggling with the first real summer vacation visitation time exhnarc has with my d12. He of course, did not choose to take her somewhere the two of them alone...which daughter hoped for and had anticipated.

Alas, he surprised her with a trip to vegas, OW and her two small daughters. OW said they were planning to "bond"...
Fabulous.

I'm doing pretty well. Making great progress and in general done with HIM, OW and their R, and the sadness of our family ending. I know its best for me and daughter too ultimately.

But since he scooped up brand new family immediately and began playing happy family as soon as he moved out - forcing daughter to play the role - this has been one more trauma I've had to deal with.

Any advise on getting through the next two weeks without daughter...feeling alone, a little lonely and hungering for her?
