I agree with Mouse's post on the fear of the annihilation of self.

However, I don't think, Sunny, that fear necessarily equates to anger. I have feared T's vacations but I don't get angry when he goes. I accept it as a normal thing for him to do. Maybe the child self is angry but the adult self knows he needs his break!

He also doesn't encourage me to get angry, but knows that the breaks are difficult for me so he attempts to help me manage the feelings that come up.

I don't think that your reaction is abnormal. Nor do I think that a feeling is indicative of a particular approach.

I think that Mouse's post relates to the fragile attachments (or lack thereof) that some of us had with our mothers that lead us to insecure adult attachments with our therapists (and probably anyone else who gets close).

I also think that the deeper the therapeutic relationship, the more attached you become and the more you will "feel" the pain of the break. Again, this is much like a child feels the pain of her mother's absence.

I think you should count your blessings and enjoy the relative calm. It's a good thing!
