@Sannah - neither confirmed nor denied at this point. My SIL and I both think YES.
C'mon, I know you've got more for me than that

@Sunrise - the core question is "why didn't you honor the relationship enough to discuss it with me?" which is something he taught me about expressing my boundaries and discomfort if they are crossed. Digging here, I asked "what would you suggest to me at this point" and he said A break.
Credibility - yes, he said "I've really lost my credibility with you" and I said Yes, you have.
Provoking - he asked me about behaviors I had at 18 yr old. I had told him before about how I acted w/older men. So I gave him an example, using him as the example (pic - from Google Street View - of the clinic he works at on Saturdays, with the store address and a time to meet for lunch at Subway. I seriously did the whole thing in 5 min at work, unlike the days of work needed when I was 18...). I truly considered not doing it, and then later to skip sharing it since I knew it was provoking, but I figured hey, you are supposed to tell it in therapy, not hide it. Any therapist would have been provoked; good ones deal with it and talk about it, like yours did, he was honest with you.
I've previously told him "All men are pigs" and he agrees there are many examples of this....

Overall, I feel like his stuff (his own things or reactions to my stuff) has intruded on my therapy just one time too many. And it's just not supposed to happen, at least not this much, and if it happens then at least be honest that "hey, this is my stuff and I'll handle on my own time, sorry for that".

I expect I'll eventually feel like having that final appt, to close things out and see if there is more clarity available.
