The reason I've fallen out with R at the moment is pretty much very similar- he stopped replying to my emails, without giving me notification after previously allowing me to have that. Maybe it is a psychodynamic thing- he doesn't believe in hugs either. Very paraphrased but someone told me previously that it was to increase the intensity in sessions.

Things I previously did include writing out messages in a notebook and then writing out his reply too, but also if I had an old email I'd mark it as unread and flag it so that it would appear at the top of my inbox and look new.
