What does Olga say when Matteo thinks maybe they need to break off their relationship after she does not communicate with him for three days?

After Olga does not communicate with Matteo for three days, he says that they may need to end their relationship. Olga tells him that she will never ghost him again. She tells him that she was wrong. However, if their relationship is real, one stupid mistake on her part should not "spell total doom" (231). She asks him to think it over, and she promises to text him and tell him why she did not communicate. If he believes she can do better, than they can continue with their relationship.
