I woke up this morning thinking about your chapter 5, Connie.
Three suggestions that could make the chapter stronger came to mind:
1. The meal ordering and clearing sentences break the story flow. I’d summarize as something like, “They gave their orders to the waiter.”
2. The flow of their conversation seems out of order. They jump from intensely personal pain to banal How was work today. The emotional needs to escalate, timid or circling at first, then bolder with probing, pulling back push-pull.
3. Since you are in Kat’s POV, she could have more introspection. Let the reader into her inner feelings. As writing, As written, the dialogue feels more like reporting, with little emotional revealing.
