I would have felt criticized and invalidated had a therapist spoke to me as you described in your initial post. First, it's absurd assuming that a client jumping topics is a grand scheme to undermine therapy.

Then I find "interpretation" a parlor game, at most wild speculation, at worst antagonism disguised as insight. No one is clairvoyant.

My therapist deftly deflected my concerns by denying all responsibility for his behavior. He blamed the conflicts on my transference.
Ruptures are particularly inequitable if the therapist is staunch in his or her blamelessness.

Fortunately I found support with friends, and cut off the dance after it became destructive.

I think these occasions require holding one's reality regardless of how an ascribed "authority" interprets events.
