He can't stop staring at me
I had a coworker/friend (?) who would not stop finding opportunities to stare at me from the moment I met him. Many things happened in our relationship, and let's just say we began to drift due to a conflict in between the two of us. He was very hot and cold and there was clearly attraction between us but it felt like he did not want to give me the time of day so I put distance.
He did not stop staring, not even up until his last day. He would always hold doors with his whole body so I'd have to inch closer to him, would breathe heavily near me, accidentally grunt in my ear, and so on. But above all, he could not physically stop himself from looking at me incredibly often, to a point where others noticed. He is a huge flirt and had some people who were clearly into him, and he was even touchy with them, but for some reason he panicked horribly at the idea of me hugging him once. No matter what I did, he would look. Even on his last days, he would find ways to circle around me so he could get a 360 view, kept randomly looking at me mid conversation with others, and once snuck up behind me as I spoke with someone before walking away. Sometimes he'd even get into specific positions and angles just so he could see me. Despite this, he never actually wants to talk to me (even after I made attempts to treat him warmly), and would often sadly watch as I spoke with others amiably. Can anyone get a read on the logic behind this body language if there is no real engagement?
