I am really sorry your "safe session" went so wrong. This may be WAAAY out there, but something different came to my mind when I was reading your post.

Is it possible that he was thinking of giving you a "loving" hug and because he wanted it to be a safe session, he wanted to make sure you were ok with the hug? It sounds like he was trying to make it the nice, quiet session on the floor that you needed. Maybe he was feeling safe and loving and good. Maybe he was feeling like giving you a hug because it seemed natural.

I don't know if this makes sense. He obviously "blew it". But, maybe the reason was something loving. I dunno:Ponder:
