Have you been backstabbed by a "friend"?

i think backstabbing is the main reason why friendships are being ruined. it is a very dangerous trait that can ruin people's life. me? being stabbed? i think sometimes but after that, my friend says it to me. of course sometimes, the friend can't just say it directly to the person for some reasons that they only knew but after that, it will be okay if she says it to me in a nice manner wherein i will not be totally hurt for i am expecting that my friend will help me in everything especially in times i needed her the most. my bunch of friends are not that type of person, we are all very frank with each other and that sometimes, the cause of gap is the tactless words that comes to our mouth but every problem in our group makes us more bonded as we go on everyday.

my so-called friend was cool with every boyfriend I ever brought around here until lately..he told my ex all the stuff I said about him..none of it was good and he couldn't help but to run his mouth..we aren't friends anymore..he thinks we are "roomates" when in all actuality, he is a tenant..and a horrible one at that..thats about to get evicted real soon..when I found out what he told my ex, I went off so bad, he got nervous..I can't stand big mouths..
