How to find out if he likes you
Know how physical attraction works.
Your brain chemistry is responsible for who and what you're attracted to. In fact, according to experts, physical attraction works a lot like addiction: both stimulate brain chemicals like dopamine and oxytocin.
Even if he's not into you, it doesn't mean there's anything wrong with you: it's all down to the chemicals. Research suggests that our brains can tell within one second whether we're physically attracted to someone or not.
