its all good man, times change, people change. thats about all there is too it....its the life cycle man.. Shit ive gotten soo close to people at some point then next thing you know bam! they fall off the face of the earth. People are put in your life for a reason, whatever that reason be they serve or served a purpose in your life and ethier they will move on or you will move on. Simple as that. I think you over analyzing the situation man, it really shouldnt be anything to get upset or think about too much. And the people that matter will stick with you through thick and thin.....
