backstabbing friends

i think i will not have that much courage to tell this to person who seems to be my friend to me.i will rather stop talking to her and avoid her calls or talking to her.even if she persists then i will let her konw what she has done.and i am sure after that she will not turn back to me since all my firneds konw that i dont tolerate a person who tells lie or is a backbitter.thats why its said that its really tough ot find a good friend in this world.

That would probably just end up in everyone feeling bad. I would just say I am sorry I can't be friends with you anymore. I need to only have people who are positive influences around me and I don't feel you are being that right now.

Sincerity - a true friend is hard to find.

usually you don't you just kind of slowly fade out of each others lives you can confront them of course but this never has good results
