While I agree with you, I think it's semantics. C could have used any other word but chose fantasy, a word that has a connotation of foolishness and denial. Would C say that it was a fantasy of she said she didn't think her marriage would be saved? I think not. THAT would probably be unknowable at best, a firm acceptance of the likely outcome at worst.
Again, I agree that C may have been trying to open her eyes to the POSSIBILITY of the end of the marriage, but to suggest that having hope for reconciliation is fantasy seems a bit unnecessary.
This is why it's hard to try to second guess a therapist. They know what their intentions are and we don't.
