Many experts claim that a guy’s pupils will dilate if he’s interested but this can be kind of tricky to assess.
Another strong tell is if he finds ways to touch you.
If he likes you, he’ll look to see your reaction right away.
You may notice he seems a little flustered or maybe even blushes a bit when you talk to him.
If he behaves differently with you than other people in his life it’s a sign that he holds you in a different regard.
If he wants to get your attention, he’ll think of something. Maybe his company is hiring and he asks if you know anyone looking for a job, or he knows someone looking for a roommate and he asks if you know anyone, or he asks if you have any recommendations for a place to take his parents for dinner.
When he wants to get your attention, he’ll think of something, even if he just makes it up.
