JBug, I learned not to pay too much attention to my T "after" sessions when we were having "casual" conversation as they're no longer thinking 100% in T mode. I know I joke with lots of people, pretending to whine "you don't love me anymore!" when I don't get my way about some silly thing; I think it's a common mock-complaint. I also amuse people with my

Nobody loves me
Everybody hates me
I'm going out to the garden
and eat worms.

I think your T was just following a formula play-type; as if you were trying to hold him hostage (you don't love me anymore. . .or you'd do/say what I want you to) and the way out of that "corner" is to say you didn't love the other in the first place so there's no leverage, way they can unduly influence you. We (my brothers, cousins, friends, etc.) use to make comments like that growing up all the time.

I'm quite sure he loves working with you and isn't just pretending. It's not possible for most people to work in therapy if they're pretending, they'd get burnt out instantly and their feelings would show no matter how good a pretender they were. You'd be able to tell in your heart if your T were pretending/insincere. Trust yourself and your T.
