I went thru something similar. Confusing. I say ask for whatever you need. Why not?

Maybe you just need a better ending and some resolution. And maybe it's more than a single session. Termination should be carried out according to the client's needs even if it takes time.

Did she suggest any options for working thru the rupture or just quit on you?
In Sweden do you have therapists who act as consultants in cases of ruptures? I don't think it's ethical for Ts to force termination without trying to work thru it.
