Vicious Circle

He was so irritated, literally flaring when he came to know that his friend's girlfriend had called him (his friend) to tell him that she was upset coz the guy she used to like was now in love with some girl. All the time he was just saying one thing "how could she? After being with him for so long she should have forgotten her past and whatever atleast she should have thought of him. How would he feel?" How upset he was for his friend.....and i remembered the day when I was talking to him on phone, walkin on terrace listening how bad he felt when his ex-girl friend introduced him to her new boyfriend.
