I am actually very glad that my therapist hasn't ever (and is unlikely to) disclose anything remotely personal (E.g. hasn't said anything about being married or having kids or what she's up to when she cancels sessions etc).

More than anything else, it allows me to keep my opinions of her personal life -- no small thing, given that I have plenty of strong opinions about the lives of all sorts of people! -- outside of the therapy space.

So, I don't have to worry if my conscious or unconscious judgment of her (and I think given my personality, there's likely to be some sort of judgment just about always!) when she reveals personal stuff will in turn influence her efficacy or willingness in functioning as my therapist.

By the same token, I don't tell her -- despite her rather irritated comments about it -- things that I don't think concern the reason I'm in therapy.

So, at least for me, I don't feel like I have to make myself vulnerable in ways or on a timeline that doesn't feel comfortable to me.

Having said all that, sure there's a temptation for me to sometimes let it all hang out and see how she reacts -- at those times, I catch myself feeling like there's a part of me that's 'testing' her.

But, remembering this helps --
a. she's human and may not have the perfect response to my stuff and
b. that if I'm really uncomfortable revealing something and I'll only feel okay if she has the absolutely attuned / perfect response, I clearly shouldn't be revealing it (again, this is just how I function and not a universal prescription).

So, I like feeling as if there's plenty of room to breathe all around.
