How do you know a guy fancies you?

Keep an eye out for eye contact.[1] Eye contact is one of the most powerful things in all of body language. Someone can use their eyes to communicate a lot of things. If someone's making eyes at you, it means he's interested in you in some way. If you see a longer pattern of eye contact, there's a chance he fancies you.

See if your crush smiles at you. Like eye contact, smiling can say a ton without someone needing to speak a word. Where eye contact usually just means interest, a smile is usually given to show warmth and affection. Keep an eye out if he smiles at you when the two of you are around each other.

Notice any affectionate touching. Light touching is often a clear form of flirting. This includes a light touch of the arm or waist, or even an extended hug. While friends may already touch often, there's an added coyness when the touching is meant as flirting
