"Bestfriends"? I don't think so.?

I think you want to hold to all memories and you don't want to see a person that you know for so long get hurt and that's why you are looking for different ways to make things better between you guys unfourty not everything I'm life is perfect and people drift apart no matter how close or for how long they knew eachother. Take a step back and view the situation, try seeing things from her view. Maybe she feels intimidated by everythin around her and she finds comfort in different things from you. Don't push a wall when it can't be moved. Continue living life and do what you think is best for you. Good luck'
