Small change in boundaries

For those of you whose T's have changed boundaries without any notice or without you having done anything majorly different what did you do?

I'm mainly talking really about things like replying to emails and then suddenly not doing that anymore without there be any change on the clients part. E.g I used to write an email to my T once a week between sessions to help get my thoughts down about the previous session. He would read it, acknowledge it and then we might usually talk about some of the things in the next session, generally only if I brought them up. It's always been helpful to get my thoughts down as I was finding it really hard to wait a week between sessions to tell him some feelings/thoughts about things that had come up in the previous session. He would usually just acknowledge it with one line saying something like 'Hey...Got it. We can talk more about our next session'. Although I would have loved a more in-depth answer he doesn't do therapy by email which I understand so was more than happy with this one line as it made me feel heard. The last two times I have emailed he has not sent any acknowledgement although has brought up the email in session and we have discussed. Nothing has changed except for his lack of acknowledgement. The email is never more than 10 lines long (I make a point of that) usually just a main thought or idea.

I know everyone will say I need to bring it up which I plan to eventually but I just don't understand why T's do this sudden change and I have seen it happen a lot. I understand when a T has perhaps been too lax on boundaries, realises their mistakes panics and pulls back (It's not okay but I see that happening) but what about there appears to be nothing like that? Is it a technique/intervention type thing? Is it that they were consulting with someone and they made them think twice about it? It's just very confusing.

My T has done this in the past few months although I have also been emailing more and longer although it started out exactly like yours. In my situation when T and I talked about it he explained that his life and his work are both much busier than they were over the winter. He wants me to be able to communicate with him by what ever means I am capable of right now while we work on being able to do face to face. When he was feeling like he HAD to read them and acknowledge them before session he was starting to feel negatively about all the emails I send. When he stopped and thought about where the feeling was coming from though it was because he resented feeling obligated to reply and pressured to read them so that he could write the reply he felt obligated to send... even though they were often 3-5 word replies. When we talked I said the replies felt good but I didn’t truly need them and I know he has been clear that if you NEED a reply you need to call him and leave a voicemail. Now that he knows I am not going to be hurt or angry about not getting a reply I have been getting more replies again. Still not every email or even every week, nothing near what it had been but it isn’t total silence any more.
My T has been up front with me from the first session that he sees boundaries as more fluid they may change with circumstances inside and/or outside of therapy but that we can always talk about them in session. He knows I like certainties and absolutes so he has reminded me that his boundaries are fluid often.

I don’t have any real words of wisdom although this exact scenario has happened to me. Obviously, as you know, you need to talk to you therapist about this because there can be so many different reasons for this change and you won’t know until you talk about it. I was pretty upset when it happened to me last fall and we have talked about it multiple times since then. That’s really the only way. Good luck!

it's honestly horrible and messes with my trust. it's why i don't trust T's anymore. they are no different than any other jerk in the world and yet we pay them to treat us this way? ya not cool

if i could have redone anything with long term T about that, id simply have never met him, my life would be so much better without ever knowing him.
