I know T's probably do this kind of disclosure because they have the best intentions. Maybe because they feel the situation has an impact on them and they just want to mention it to their clients. In this way disclosure has been helpful to me, because it makes the risk a bit smaller that I would think I make my T feel bad or I would feel something is going on and it would bother me not to know what it is and how serious it is, etc.

But I don't like it when it happens though. As you already mentioned, it can make a client wonder about how to treat their therapist and that can have a big influence on the therapy itself. While therapy should be all about 'you' and not about you trying to do or tell the right things, being extremely careful, etc.

No matter how much I appreciate my T sharing things with me, I sometimes wish she wouldn't. I'm already pretty bad at showing how much I care, so it makes me feel very uncomfortable.
