Ending Friendships

Sometimes friends drift away, or break up. When you meet a new friend and become close do you really expect things to end

 and the situation appears normal? No of course not, but it happens and usually you accept it and spend time with other or new friends. Although what happens if one of the friends is not ready to drift apart and say goodbye? Sadness. At least that is what I expierience. Especially since I have no clue if it has ended or not. If it has ,it was cut too short.
