I hated the first time back for lots of years because I felt so awkward and confused. The whole war thing going on so you didn't know if you should act like a spurned infant and "ignore" T for a bit (see how she liked it!) or pretend nothing had happened, or give in to the feeling of relief T was back, or what. I hated that feeling. Eventually, as I got better at being "myself" before she left, the coming back was more "natural" too and didn't get so tangled feeling so just segued into the session at hand.
