When you first started with your T & you stated that the behavior had been going on for x years.....that was prior to this T.....the way I see it is that NOW T realized the extended amount of time in HIS REALITY WITH YOU that the behavior is continuing to be an issue.

Sometimes even when we tell them it's been going on for so long....they need to process it into their own reality with you....sounds like that was what he was doing IMHO.

I know that I went through a horrible trauma while I was seeing my pdoc & my psychologist (who was having back problems just before back surgery at the time)......then all minimized the trauma I was going through & excused it away to my lack of eating....but my lack of eating was because of the stress I was going through. I ended up in the medical hospital because of the anorexia.....& the nightmares I was having from the trauma were horrible......but one doesn't have PTSD until a certain time after the trauma.......they were having a difficult time figuring out how to Dx what was happening to me because it was all in real time & hadn't met the specific criteria that it needed to meet in their minds to qualify as anything but a horrible situation & anorexia.....but I was living the horrible terror & fighting all the Dr's regarding the condition of my mother's cancer with absolutely NO SUPPORT from anyone.....& they just didn't get what I was telling them.

Just like for me....it became more clear as time passed & it was more obvious of what had been happening......& they needed to SEE the progression with their own eyes & ears...not clear in real time or just from things I had commented about in the past because I had gone through anorexia issues previously for a completely different reason & circumstances.

Think your T is just now getting a more clear picture of what you are dealing with & the causes that surround the ED behavior which is really the most important aspect of the treatment.

Therapy can be so difficult because we don't see always where our T is coming from & what their logic is behind their thinking......hope you can maybe ask him about this & get a better understanding of where his thinking is coming from.
