The person might not be who you thought they were; might have changed for the worse; but in the memories, they will always be the person you loved. it's ok to cherish those memories. You dont have to allow that person in your life now.
I'll always miss my best friend. But he chose to walk away and now it's time to live my life and find someone who would never be able to walk out. Because if you can walk away, you were not who I thought you were anyway.
So true! Why do people not understand this! People change everyday because they realize things and become more mature! Not because they are becoming something of a monster! Just deal with it and eventually you will see the same things.
