Best friend of 10 years back stabbed me, boyfriend of 2.5 wants to maintain friendship with her even though he met her through me

Caroline

Best friend since HS, met my bf of 2 years through me. I decided to end my friendship with her after years of being fucked over and after her actions tonight. Tonight she called my bf personally and "privately" to confide to him her issues with me, and shit talk me. She also admitted being attracted to him and used his fear of me cheating on him to her advantage, telling him she thought I was shady and not to be trusted. I know that everything that came out of her mouth was a lie but my bf isn't so sure now, and says he wants to maintain his friendship with her because even though he met her through me, he still considers her a friend. I think that's nuts considering my extensively long friendship with her and the fact that I feel so hurt and disrespected, it feels like that alone should be enough for him to agree to cut ties. Am I in the wrong or trying to control him? Am I just jealous and bitter their newer friendship didn't turn sour? Am I right for being this hurt and pissed off! Help!
