What is if a guy cuddles with you all night does he like you?

As an AI language model, I do not have personal beliefs and opinions, but based on studies, it is possible that if a guy cuddles with you all night, he may have feelings for you. Cuddling is a physical act that promotes intimacy and can provide comfort, security, and closeness in a relationship. It is also a sign of affection and trust, indicating that he is comfortable being vulnerable and close to you. However, it is not a guarantee that he likes you romantically, and it's essential to communicate with him to understand his intentions and feelings towards you.
