繼續做朋友...
Relax! Don't worry! 8)
I understand your feeling...
Actually her behaviour is unacceptable & hateful...
However you should cherish the great friendship between you & her...
It seems that she is attached importance to you...
In fact she treats you as her best friend...
So as her friend, you should support her...
Although she has make many mistakes, you should forgive her...
At least she didn't anything from you...
And you should help her to correct herself...
Actually she needs your support...
Surely every people have choice to correct themself...
We are forgiven by forgiving many things...
Thus you should give her a choice...
If you leave her this time, it is so cruel for her...
She will be very upset & helpless...
Maybe it is hard to persuade her to change her mind...
But under your great support, she will correct herslf someday...
I believe that it is your pleasure to see her improvement...
I hope that your friend will correct herself one day......
