mutual

The word "mutual" is used in two slightly different ways. First, it can mean something that two people share, like a "mutual friend." This means the person is a friend to both of you. Second, it can describe a feeling or action that is returned by another person. For example, if you like someone and they like you back, the feeling is "mutual." It is most commonly used as an adjective before a noun (e.g., "mutual respect") or after a linking verb like 'is' or 'was' (e.g., "The feeling was mutual").
