What is when your ex returns your gifts?

As an AI language model, I do not have any personal experience. However, when an ex returns your gifts, it can indicate a few things. It could be that they are trying to move on and let go of any remaining emotional ties between you two. Or, it could be a form of closure for both parties. Additionally, they may feel guilty for keeping the gifts or want to relieve any feelings of indebtedness towards you. Ultimately, returning gifts may provide a way for them to mentally and emotionally distance themselves from the relationship.
