I think most gown ups fail in love at least one time in their lives. You didn't? Thank God about that. Well, actually, you may be not the one who is blessed. Maybe the people who tasted the bitterness of love are the blessed. I remember that I closed my mind for a long time since I lost my first love. Yes, I loved my first love so much, I really regarded her as my destiny. When I lost her, I felt as if I lost everything in my life. I am sure you also have some story in your heart. I thought I would not meet other girl again. But, before long, I realized that I needed love and I needed to move forward. But, it also took a long time before I accept my affection toward another girl. You know the reason. Yes, I was afraid of being hurt again. Eventually, I fell in love with another beautiful girl again though my relationship with the new girl was definitely different from my first one. Unless you open your mind to other people, unless you give him everything you have, the chance that you are going to gain his love is very slim. I know you were hurt, but you will never be able to be happy again if you don't open your mind to another person. And I don't worry about that very much either because I know time will do a lot of things about that. Have a wonderful day.
