No, it doesn't necessarily. So your T cut off conversation and then added that you couldn't ever talk about the subject at a subsequent meeting as well? That seems kind of strong.

In motivational interviewing, one of the first signs of change is that the client is willing to talk about whatever he wants to change. It is considered a good thing, and that there won't be action or change until the client starts engaging with the topic. This is called "change talk" and most T's encourage it. So if you are beginning to broach an issue you want to work on or change, even in the distant future, that would be encouraged. Is that kind of like what you are going through, SAWE?

If the conversation is some kind of ongoing "argument" and the T has expressed her point of view several times and the client keeps trying to argue her out of it (like regarding texting or email policy), then I can see the T cutting off conversation. This would be a boundary issue.

It might be easier to understand the situation if we knew, broadly, what the topic was?
