If you're wondering if a guy is trying to make a move on you, there are some definite signs to look for. First, see if he's making eye contact. If he's looking deep into your eyes and holding your gaze, it's a good sign that he's interested. Another sign is if he starts touching you more often, whether it's brushing your arm or leg or leaning in close when you're talking. If he's doing this, it means he wants to be closer to you physically.
Another clue that a guy is trying to make a move is if he starts complimenting you more. He might compliment your looks, your clothes, or anything else about you that he finds attractive. This is his way of letting you know that he likes what he sees and wants to get to know you better.
Of course, the best way to tell if a guy is interested in you is simply by asking him out! If he says yes, then it's pretty clear that he likes you back and wants to take things further. If not, then at least you'll know where you stand and can move on accordingly.
