I work at a point of sale, every day a guy comes and buys something and shows interest, he stands from a distance and looks at me, does not smile, does not talk. done it for over a year. start wondering if he likes me or is here just to shop?
His body language in repeatedly coming to your place of work for over a year and staring at you would indicate that he is attracted to you. However, simply being attracted to you doesn’t automatically mean that he likes you.
There is a chance that he is already in a relationship or isn’t at a place in his life where he is prepared for romance or a relationship, but finds himself attracted to your looks.
He maintains his distance without smiling or talking because he doesn’t want to escalate the situation to a point where he could find himself tempted to go after you. By maintaining his distance, he is able to admire you from afar without running the risk of getting into anything romantic with you.
