Probably more of a luck thing? personality thing? Who knows? One of the great mysteries of life. I haven't ever had ruptures with any of my therapists either, certainly nothing I would call a rupture. Sure, there are times we disagree and talk it through, but I don't consider that really a rupture -- just part and parcel of any relationship, including that with a therapist. It was never something that I found highly upsetting, considered leaving over, feared discussing, etc. (And I definitely needed therapy! LOL!!)
