What is Unsent Letters

The unsent letters are symbolic of Ryan’s emotional availability and how he is unable to accept his role as a father. Ryan is open with the fact that he never wanted children, but he makes initial efforts to support Andrea during the pregnancy because he loves her and thinks it will keep them together. When Ryan leaves, he writes letters to Andrea and Lucia that he does not send because he is unable to commit to telling them how he feels because he fears it will hurt them.
