It will take time, but stick with it. Maybe she is angry at Daddy for moving out, and doesn't fully understand and as you say your son is different about it all. It may be a generalisation, but girls seem to see their dad differently. As long as you two are amicable she will soon see that it is better like this than it was when you didn't get along.
Could it be her way of trying to show you that this is not how she likes it (us girls can be little minxes like that you know! ;-) ) Persevere, one day she will be fine, you just have to bear with it for now. I am sure it hurts her dad when she is like it too, but you will come out of the otherside - honest.
Maybe she could have things to tell him when he gets there, how good she has been, what she has done etc., just a few minutes for her to tell her dad things?
Good luck.
