An intimate relationship can be described as:

An intimate relationship is characterized by emotional closeness, deep understanding, and significant trust between individuals. This closeness often involves sharing personal thoughts and feelings, leading to a strong bond that goes beyond mere acquaintance or casual interactions. In contrast to a casual friendship, which might not involve deep emotional connections, or a relationship with many people, which can dilute intimacy, the term "close relationship" specifically encapsulates the depth and personal attachment that typify intimacy. Additionally, while online interactions can be intimate, they do not inherently define the nature of intimacy itself, which primarily revolves around emotional and personal connections. Thus, describing an intimate relationship as a "close relationship" accurately reflects the depth and bond that is central to intimacy.
