*dances a little euphoric dance*

That went REALLY well. He didn't mind me speaking English - he thought it a little odd and said it's something he'd like to explore with me but he certainly didn't have anything against it. I gave him the letter, and he read it, and said that he thought it was absolutely fine for me to bring something like that. We didn't discuss the contents - which was fine by me - but he kept it for future reference. He asked me some difficult questions and gently prodded me until I'd answered them or at least addressed them; he did this in a very respectful manner but without allowing me to cop out. I found myself telling him things that I've told nobody else, ever, and I felt validated by his responses.

And at the end he asked me if I might consider continuing to talk to him - that is to say, he offered to be my T. Which was exactly what I wanted.

I am so relieved. Thank you all for your support.

(Of course it's almost June which means he'll be off for his 6-week holiday in a few weeks... but I don't think that will be a problem. I'll see him one more time before he leaves, and he'll be back in August. It would have been better for me to continue immediately but on the other hand we won't be in the middle of any difficult processes that would have to be kept on hold.)

[ETA: I forgot to mention that nobody exploded.]
