Thanks for the concern lyib, and others who said this. I think you're right, he should remember whether my parents are together. He pays attention to childhood stuff, so it shouldn't be an irrelevant detail to him.

I think he's an intuitive person who might tend to remember impressions more than specific details. I can definitely forgive forgetting specifics this time. He was very sensitive and supportive. I almost didn't bring up what I was going to say but he noticed that I barely started to say something, and asked what it was, so I did.

So I think I'll take Splintered's advice and pay attention if it happens a lot.
It's funny that my impression of him when we talked to him before (last year) was that he had a really good memory, especially because he doesn't take any notes. I don't remember why I thought that though. I am afraid he thinks I'm boring, and I have to try not to let myself go there and blame myself if he forgets (more than I want him to forget).

Yes, that makes sense lyib and I will try to keep it in mind. I wonder if he doesn't know how strongly he comes across to me since he's more extroverted. But now he knows he had enough impression that I was still upset about it a year later. It seemed like he was really trying to help me feel more comfortable even though I didn't bring this up until 5 minutes before the end of the session. I think he gave me extra time but I didn't look at the clock when I left. He told me some things about his childhood and told me how old he is- almost the same age as me- which helped me feel a little more equal with him.

Oh, and another good thing- I asked him if he looks on any websites where people post about therapy- and he said no . He said he thinks that it can be good, almost like a group. Then later he asked, so you spend a lot of time online? yeah, yeah
