#1: Watchful Eye
When a guy looks at you in the eye, it sometimes means that he is interested in you. Usually, men don’t look women in the eye if they aren’t interested. This doesn’t mean that he is arrogant, but it’s just that he isn’t intrigued.
However, if you catch him staring at you repeatedly, you surely have something to think about. According to me, a man staring at you is one of the first signs that he loves you.
A guy becomes restless in the presence of a girl who he loves and relentlessly tries to show that he is just looking around while what he is actually trying to do is to get a glimpse of the desired person.
