Hi Peaches,
Just wanted to say that I have every sympathy with you. If your T had been allowing email contact all this time and replying in a certain manner, then to change it without explaining why is not very helpful or beneficial to the relationship. If T did feel that it was getting too much or realising she had created a dependency in the first place, then that is not your fault and she should have approached it properly with you and explained how it might help you to try to rely on her less, rather than to make you feel like you did something wrong regarding boundaries. My T had always let me email between sessions, has always encouraged me to email as much as I want and always responds in a thoughtful, detailed manner. If she were to suddenly withdraw this, I would be devastated to say the least. I would be so hurt that she had suddenly changed and that would be more of a problem that the actual emailing itself. So I totally get where you are coming from and it's not a nice situation to be in. I don't know what to suggest really, other than as someone else suggested, asking for a paid email session per week just so you're both clear about it. I have never paid for emails but I do pay for any phone calls to T. If your T wanted payment for emails, it is up to her to let you know that. Anyway, just wanted to say that I get it.
