What do you expect from your friend

I expect my true friends to be honest with me all the time and not keeping any secrets from me. Coz it feels bad to know that im the only one in the group who does not know the story like they all know and they didn't tell me. She also has trust on me. Coz if she doesn't i can't consider her as my friend. How can u be friend with a person who doesnt trust you, ryt? And most important she should not be a backstabber.
