Ruptures are hard. I went through a period of a couple of years where it seemed like we had some sort of rupture every few weeks. We always worked through them, bc my T is awesome. Longest rupture was maybe 2-3 months? But once we addressed it it was resolved within a session.
I think length depends on the relationship. I have a solid alliance with my T and it’s increasingly easier to address her missteps.
If you like your T and feel you have a good therapeutic future, then talk about it. And continue to do so until you feel resolved.
Good luck!
