Best friends friendship?

Anonymous
I have this friend who doesn’t let go of friendships. And she complains about all these people and what they do but you’ll still see her with these people if someone apologizes to her then whatever you did is fine. No matter how many times they apologize.
She had also told me a year ago she hadn’t like her friend but chilled with this person all the time. And says all these people are not her friends.
One fucked her ex man while they were trying to get back and she s to lol considered this person a friend
My concern here is her because why does she let these people back in her life and then still come and complain she will even say I will never see them again next thing you know they are together.
Is she a red flag? Or do genuine people do this?
