I had that with ex-T a fair few times.. one session was particularly painful and we sat in silence and she just watched me squirm and hurt for ages - eventually stating that she could see how hard it was for me - without ever throwing me a lifeline.
It's hard, I know!
I don't have any advice right now, but I'll sleep on it! In the meantime, I like MKAC's links (if you're reading, thanks for sharing those)!
