That actually has a lot of information I haven’t seen before. What I have seen before was pretty much saying just that police had no idea if she had eaten the meal herself, and did not know if there were mushrooms in the meal, and made it sound like she was not providing answers that she should have been able to. That extra information could make sense of that - if she was hoping for reconciliation and then the ex has not shown up she could easily have been too upset to eat, have spent the meal pushing food around her plate and have no idea afterwards if she has eaten any of it.
