What do you think of this?

This guy and I had a deep chat, he told me about his life and was very attentive in the conversation, he kept saying my name and showed interest in what I said. He had been displaying signs of interest in me before but we had never got the chance to have a one-on-one chat. He told me he was a year younger, I kept saying I was shocked by that and he was wondering why I was so shocked and seemed disappointed, he then said that I look a year younger than him, unfortunately he said that he wasn’t looking for a girl as he will be moving country eventually. Afterwards I started flirting with this guy that I know he thinks I like (I have no interest in him really), I then started flirting with this other guy and I could feel him eavesdropping, he then stood up and looked right over at me (the guy was dropped over me talking); I then started talking to the other guy again, he looked at me, then at him so see what we were doing and after a while got mad at that guy over something small. What’s your opinion of this?
