Now he wants to take her for a nine day trip and I don't know what to do. It seems like way too long for her to be away from me, but I'm not sure if that is because of my own attachment or her best interest. I know she loves her papa and has a great time with him. I also know that she misses HIM after a few days, and imagine that she would REALLY miss me, her constant companion these 4 years.
What I'm looking for is outside support for his point of view or mine. By the way, he is unwilling to compromise on the amount of time he wants to be gone.
