My exT's reaction:
- at the first session I told him in few sentences about the reason of the therapy (csa) - he was absolutely okay with that
- after some session, I told him a bit more - he was still okay, like not a big deal and we have to understand why I reacted how I did etc.
- I gave him two examples in details - he was terrified, cried, said that within 30 years of experience he had other clients with csa history but nothing even half as bad etc.
- it ended up that he was not a good T for me and sometimes I am not sure if my story wasn't just too much for him...

My current T:
- before the first visit I sent in the e-mail the very triggering sentence which my previous T told me (I've even posted it here), so she knew what kind and l"level" of the abuse it was
- My T does only quick diagnosis or trauma work, so I am sure she is much more experienced with such stories
- she doesn't know much details, she makes sometimes very sad face but hasn't cried (yet). I hope she can handle a lot because the experience with my previous T was not so cool...
