Frankly, I'm friends with Bestie because I know she believes that too. As frustrated as I am with her right now, as much as I think this is a major issue in our relationship, I truly expect that she will at least make a serious attempt to hear & understand me when I talk to her about this.
I want to talk to her about it, because while it's possible we might fight about it or one or both of us may get our feelings badly hurt, I don't think either of us would throw out a relationship that easily.
