There's definitely a point in talking about it--if it's bothering you and affecting how you're feeling, you should tell her. She may have a really good explanation for all of it that has absolutely nothing to do with you. I agree that the guy who came in may have just been there to pick her up or bring her medicine or something.

I think of the many times my marriage counselor had to cancel--sometimes at the very last minute--when his wife was sick. He wasn't clear about what was going on at the time, but my ex-T clarified on several of those occasions that it was a family emergency, that it was something only he could deal with (she clarified to me because I'd recently told him about the transference and was concerned it was him not wanting to deal with me). I later found out about his wife, and it all made sense. I wish he'd just been more open about it at the time though. In a way, I get why he wasn't, but I also feel like he needed to consider how his clients felt, with so many cancellations. I wouldn't be surprised if some bailed on him because they felt they couldn't rely on him. (Had it not been for the strong transference, I might have considered doing the same...)

But, please try talking to your T. And stay safe.
