Tease you / try to make you laugh
Pay attention to see if he gently teases you, because this could mean he's attracted to you. Although, if he teases other girls, it might be a tactic he uses for flirting. If you're the only girl he teases or tries to be around, chances are he's interested.

Watch for Their Eye Gaze
Like touch, eye contact triggers the release of oxytocin. When someone is attracted to you, they subconsciously will try engaging in lots of mutual eye contact. They do this to feel closer to you, and because they are interested in you and what you are saying.

Men who are interested in you will likely face directly toward you during conversation. Even if you're with a group, he might turn his whole torso to face you. Watch to see if he's trying to “close you off” and keep you to himself.
Maintain eye contact.
Normal eye contact lasts for about three seconds. However, if you can hold your crush's gaze for four and a half seconds, they'll get a powerful cue that you're flirting with them. You can even hold it longer, if you like, as long as your crush doesn't look away.
