The Gap Widen

Its about my first and best Girl's Friend. Its not like last times. we shares our problems.. I will tell her anything about my feelings that i cant tell to anybody else.. I shares my tears with her that I don't shares with others.. I cant keep my self cool when somebody hurts her.. but I'm so unfair.. I'm not always by her side when she needs my help, when she needs a good listener.. a good adviser..  Am I a good best friend..?? Should I call myself as her best friend?? Am I deserve to get the title as her best friend??? I realized that the gap of our friendships getting wider and wider.. day by day.. Its all my fault that makes our friendships not like usual.. Just Put the blame on me.. I deserve that..
