Marriage counseling

My husband and I regularly(once every two weeks) go to marriage counseling to better our communication and learn better ways to work together instead of against each other. Our counselor wanted to do separate sessions this week and I’m nervous to go alone. Typically we go, learn some new info and use that to try to talk through an argument/disagreement we may be having. But since I’m going alone tomorrow morning i don’t know what to expect. Has anyone gone through this? What was it like going by yourself? Should I have things/topics ready to talk about before going in?
