"She was so jealous, she broke us up!"

So my BFF and I have been friends for about three years when I finally got a BF. She went crazy and acted so possessive of me! Things were going really great with my BF and I. My BFF started get mad and insanely jealous that I was spending time with him. So she wrote him a page long letter saying I was cheating on him and that I never cared about him. Which was SO not true because I really liked him. He figured since she was my "best friend" she wouldn�t lie about that and a bunch of other girls backed her up. He broke up with me, so he wouldn't look stupid if it was true! So I was heartbroken by two people for nothing. How could my BF do such a thing? But no worries 'cause me and Ryan got back together after a couple of days after I explained what happened.
