Mightn't he be away for the holiday? Even if he has email he can access from anywhere, he might not have brought a computer, or he might not have internet access.

My therapist has gotten very good at volunteering that sort of information at our opening ceremony of "Do you have anything you need to tell me?" But he wasn't good at it until pretty recently.

I'm sure it's nothing personal, and that he's not upset with you. If he wanted you to email less, wouldn't he have brought it up at session rather than simply changed his behavior?

I'm sure it will be ok, even if it feels rotten right now.
