Thanks for all the advice and perspective. It seems that the best apporach is to either confront her in session or just assume I've explained my point of view and not go in lenghts about the guilt in my emails.
I can imagine it doesnt bother her as much as I worry it does. I dont ask for a reply, she can chose when and if she reads them and she still does even though I technically wouldnt have a clue if she didnt.
And for me? I love how open I can be and for the most part I love that she doesnt reply so I am free to talk about anything and everything.. There are times when I would like to pay for her time to reply but most of the emails: i just want to be heard and understood. The emails made me open up so much more in sessions because sometimes it takes weeks of writing about something to finally get comfortable talking about it... and to be honest thats the biggest benefit of emailing. Of course I release my stress but mostly prepare myself to be open in a conversation. Its easier to talk when an issues has been pre-introduced
