Goodbye friend

I dont think i have ever been this frustrated with a friend in my life. I never imagined this person would make me look like an idiot. I never imagined saying goodbye to this person. Its tearing me up inside because when you have alot of memories of someone and you have to let them go, its not easy. Thats what i did tonight, i deleted this person. The thing that is going to bug me now is me and this person all have the same group of friends and now that i've deleted her, i have a feeling i'm going to be asked why i did it? i dont think i owe anyone and explanation and the town i live in, once you say something it will get to another, this person knows what she did. It cant be taken back. My mom tells me things will get better but its not looking that way right now. I cant trust this person anymore. I'm finished. Our friendship is finished. Goodbye friend.
