Think I found my fake friends

I made a post on Facebook today that wasn't directed at anyone in particular. It just said "I can't stand people who act like your friend to your face, and talk shit behind your back." I had 6 girl friends message me saying "I'm sorry, it wasn't like that." Or something along those lines. Some of these girls who messaged me, I thought we were close. I would never have guessed they talked behind my back. This is why I don't make friends😒🙄
