I have had lots of ruptures. With my last t she didn't show up one day after a three hour drive to see her, managed to repair this rupture but the next one wasn't something I was willing to work on with her and I ghosted her. She never contacted me again and I am more than ok with that. She sent me a friend request on Facebook and then when I accepted she denied doing it and said it was by accident. That sometimes she looks at clients profile pictures which is highly unethical and must have sent the request by mistake. I didn't even try to repair this because she took no responsibility for her actions and instead chose to lecture me in boundaries. I said you asked me to be friends, remember? And I never went back, I should have reported her.
Current t and I have had so many ruptures I can't even count them all, it's usually from some sort of misattunement. We have managed to repair them all so far, and it has made us closer. I think that if you can talk to your t at all and try and work it out without walking away this will be rewarding for your relationship with your t, sometimes ts can't take responsibility for their mistakes and cause more damage though.
