My friends talk behind my back
Basically I have one true friend who tells me everything, including the stuff our other "friends" say. When they have sleepovers, my true friend will ask why none of them called me to invite me over and they say "who cares about her?". They never call me to do anything and i know they always talk about me like I'm their trash. Yet everytime I'm around them, they're nice to me. Is it normal to have friends like this? For the record, my true friend and I are no longer friends with them, they're two-timing, backstabbing, awful people.
