My Best Friend Thinks I Stole Money From Her And Made Out To All My Other Friends Im A Thief And A Liar! I Havent Stole From Her And I Never Would. What Can I Do? Shes My Best Friend And Has Cut Me Out Of Her Life.

I've always told my friends that I'll only explain myself once and that if you don't believe me, I won't dance circles around you trying to prove it.
It feels good to have friends but they all mess up once in a while. Keep a cool head about you. Let them think what they will think and move on with the life around you. If they bring it up or accuse you, ignore the accusations and don't defend yourself like a lunatic. Just tell them calmly and to everyone, "I told you the truth, and I'm not going repeat myself over and over. If you can't seem to trust me and believe me, then maybe it's a good thing we're not friends. Because that's what friendship is based on."
Let it go and keep being the person you are. He or she will eventually come around and when they do, have him or her acknowledge that they were wrong and have them explain that to everyone they spoken wrongly against you. Above all, when he or she comes back, BE SYMPATHETIC! You were once best friends! Let that past fact remind you that you once were in each others pockets. Believe me, your relationship will strengthen after that.
Yet,if your "best friend" doesn't come around, it may be better that it doesn't. Friends shouldn't treat another that way and you are better off finding some one else who is worthier of your time and friendship.

I am going through this same thing myself. My best friends girlfriend is accusing me of stealing money from her, but worse is that it happened over a week ago and when she first realized she was missing the money she had said she believed that I didn't take it. Now a week later I'm hearing from other mutual friends, and even my own family members, that she is telling people she is 100% sure I stole it. I have tried to call and talk to both her and my friend about it yesterday and today, sent texts and left messages on their phones, but neither one of them will return my calls. I don't know what to do about it? I'm being made out to be a liar and a thief to all of our friends and it seems nobody will believe me! I've never felt so bad about something I didn't do.

I know this wasn't much of an answer but I can relate to the OP's situation and I needed to vent somewhere!!!

Wow that's what happened to me but worse! One friend says she thinks I stole makeup from her.. Next thing you know I have 2 other friends saying there missing large amounts of money when I was supposeably there.. Weird huh? Funny thing is the first girl who said I stole from her happened to be there  the times too when it was stolen. I think she just said she got money stolen too to put it all on me. Now I lost all my friends, I even got jumped by like 10 girls cause of that but it wasn't me! I feel you and it sucks for everyone to think that about you when it isn't true! I made a mistake and retaliated because I was so mad but it didn't make me feel any better except when I got to punch one of the girls in the face but I ended up spending the rest of my saturday night in jail! So yeah I think you should just say F it and move on with your life hopefully one day she will realize if not who cares as long as god knows the truth

Hey, this kinda thing happened to me too :) glad were in the same boat as I'm really pissed about the whole situation.....

BASICALLY.
My friend thinks I stole her sunglasses because I was the last one to look at them... Or so she says! She threatened me saying 'if I find out you did take them... You know what I'm like' and I was like oh please.... (thinking in my head) why the hell would I want your stupid sunglasses in the first place!!! So yeah I still haven't resolved this but I would like to know the answer! I think I'm just going to be patient and like yeah stay out of her way and when she finds them and asks for my forgiveness she will get NO SYMPATHY. As she has made me have no friends. So just know... Were kinda in the same boat :) no worries
