If you wanna know if a man is truly into you the first step is to look closely at his facial expressions during your interactions
specifically his pupil dilation as this can be a major indicator of interest and arousal.
If you notice his pupils dilate when he's looking at you this can be a definite sign that he likes you. Additionally if he raises his eyebrows licks his lips when he's talking to you or smiles in a way that reveals all of his front teeth then you can bet he's into you.
