You will often witness a spark in their eyes when they are looking at you or having a conversation with you. They will smile at you as if you are art personified. You can tell if someone likes you if you can sense them looking at you even when you are pretending not to notice.
"Many times people who are not particularly fond of you have a hard time making eye contact," Craig said. "These individuals often seem distracted or disconnected while speaking and engaging with you. Their eyes may shift to other things happening around you which indicates a lack of respect and attention."
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.
You can tell that a shy guy likes you if he gets extremely nervous around you. He may suddenly start behaving awkwardly or clumsily. This kind of nervousness comes from wanting to appear cool and do things right in front of you, but failing miserably at it.
How does someone act when they are attracted to you?
Mirroring your behavior
When someone is attracted to you, they'll subconsciously adopt some of your mannerisms and behaviors. To create a bond or feel more aligned with you, your love interest might hold their coffee cup like you, use the same phrases you do, or even mimic your stance.
Prolonged eye contact, raised eyebrows, and dilated pupils are all evidence of attraction. A person might lick or bite their lips or look at your lips if they're attracted to you as well. Open body language and facial expressions are also signs a guy or girl is feeling attraction towards you.
Why we feel instant attraction to some people, and not others, is affected by lots of different things: mood, hormones and neurotransmitters, how alike we are, the shortage of other partners available, looks, physical excitement, and the proximity of geographical closeness.
A guy might be sexually attracted to you if he makes flirty eye contact with you and can't stop smiling around you. He might also like you if he touches you often and makes an effort to lean in close to you. A man is probably sexually attracted to you if you catch him staring at you or scanning your body up and down.
If you notice he is making more eye contact with you or you catch a guy staring at you, he is probably attracted to you. He may be enthralled by your good looks and may be fantasizing about kissing you. Perhaps he stares at you and smiles; that could mean he likes you, too.
One of the obvious reasons why a guy may ignore or act disinterested in you is because he feels you are too good for him. He lacks the confidence to approach you or share his feelings with you, fearing you might reject him. He feels that sharing his true feelings might ruin your friendship with him.
Any person that likes you will want to touch you all the time, and not in a intrusive way, but more of a sensual one. And when a guy touches you a lot, it's usually pretty evident that he's really into you. If you feel the same way, then go ahead and touch them back.
Subjective sexual attraction: when you have sexual feelings toward a specific person based on your personal experiences with them, such as in relationships.
Objective sexual attraction: when many people find someone sexually attractive (e.g., a movie star) but you may or may not do so.
How do I know if I'm physically attracted to someone?
Ask yourself if you're physically attracted to them.
Everyone has physical preferences when it comes to romantic partners. If you look at them and think about kissing, hugging, and cuddling with them, you're probably attracted to them. Physical attractiveness is subjective and different people like different things.
High levels of dopamine and a related hormone, norepinephrine, are released during attraction. These chemicals make us giddy, energetic, and euphoric, even leading to decreased appetite and insomnia – which means you actually can be so “in love” that you can't eat and can't sleep.
