How do you know a guy is guilty. So this guy I liked said to me that he likes me too and so we got in a relation but he left me when he befriended this beautiful and hot girl. I don't talk to that guy no more but I still see him often on several occasions. He stares at me a lot even when he's with his girlfriend and even when he's not with her.
It just annoys me so much that he would even dare to look at me after he left me for a girl who is better looking than me. Why does he still stares at me for around 4-5 secs and looks at me when I'm not looking at me and then suddenly looks away when I catch him. He needs to stop doing that! When his girl and I'm together as on a occasion, he would be staring at me.
Why do guys do this? Guilty or what?
