If it was briefly mentioned several months ago, then not again till recently, it's understandable that t might not remember. Even if t were to take detailed notes, I wouldn't expect him to remember it so fareal down the line without further mention during the passing months. That said, if t were to again forget after having spoken about it now, it's less excusable...

If it bothers you though, I would bring it up. It's causing you to feel ignored, which to me is a bigger issue than t's forgetfulness. We go to therapy for various reasons, but the general thread connecting them as is desire to have our stories heard...

My t seems surprised any time I bring up my past eating disorders. I tend to attribute it to 1)not talking about it too often, and 2)them not being active often any longer. If t were to forget I self harm or forget my csa, I would be worried (both are active topics of conversation nearly every week).
