Dating and Relationships

How can you tell if a guy loves or is interested? You observed him when you were status and discussing with a buddy. You think he observed you, but maybe it was your creativity or just unrealistic. He considered you at about one time you saw him. Your sight met for just a short time, and then you seemed away. When you seemed returning up, he was discussing with some other individuals. Was he viewing you as you mingled? Or were you creating that up? How can you tell if a guy likes you? Why are people so difficult to read?
