Human is like this, only you in the same situation, then you can understand the meaning of "put yourself into others shoes."
A friend told me, she lost a lot friends. i told her, "Never mind, those will left you away, is just no fate with you..."
Fate, i push all kind of relationship matters to this word - Fate.
Everything happen must have a reason, same with why somebody will come into your world and left you in a short while.
Not all the people you met, you spoken with, will become your friends, and not all the friends, will become your mate for the long time.
Someday, somehow, you will know that, after all this, you still are the one to carry on, with or without mate.
