I understand being upset, you are entitled to your feelings. I also think it’s perfectly understandable to bring up anything in therapy and anything could be a topic of therapy session, including clients upset with therapists.

Everything could be discussed in therapy but it’s still does not negate the fact that it’s her personal life and she is under no obligations to share her personal life with clients. It’s not her session. It’s yours.

You can and probably should bring anything up including your feeling of being excluded or rejected when people don’t share with you. Hopefully she can help you to work on it.
