Yes, she is a close friend. I dread to think what she says. I'm no perfect but she can be petty bad difficult. She constantly runs people down and I feel I am unable to ignore my gut feelings about this.
Do you have any mutual friends that you could ask if she has said anything about you?
Or if you don't feel that you can do that then I'd be looking to distance myself from her.
I have a friend who gossips and runs everyone down, so about 5 years ago I made a conscious effort to distance myself from her a bit, and to tell her less about myself and my life, so she had less gossip fodder.
Flexible as in not fussy about where we go etc, she enjoys same social activities as I do. Can be fun. She had a terrible childhood and is damaged by it. Kind, generous but constantly runs down other people and leaves me feeling drained more often these days. She is my only friend. I also feel she only wants me when there is nobody else.
If I did ask her friends what sheets had said about me, I feel the wouldn't tell me but tell her I had asked. Her friends are an alcoholic, a Lady that sleeps all day and has depression and the have a very odd friendship.
