No one can know for sure. I think this is a good opportunity for emotional regulation for you, in this moment. You sent it, now you can't control the outcome.

If he doesn't respond or acknowledge this in any way, how are you going to cope w/that? Are you okay with this?

I'm still a little fuzzy on if your T knew that he declined your FB request, but thought sending this would result in something different.

I say preoccupied because you created another thread about him.
