I didn't have a "rupture" for 5.5 years with the same T, until now. It takes a lot to upset me and I loved her a lot.

I don't know if it even counts as a "rupture" or more of realizing that maybe the relationship was not healthy and didn't have any boundaries... And I got hurt really badly.

I think for me the things that caused it, and the ONLY things I can't move past, are dishonesty and complete inconsistency. I'm terrified of abandonment but I think I could have dealt with that easier than her dishonesty (because she didn't want to tell me the truth) and constant backtracking. That's just confusing and a mind**** from anyone, let alone your therapist.
