My Boyfriend .

So Heres The Story ... My Boyfriend Had A Girl Bestfriend for 4 years. Before i even came in the picture . Me and his Bestfriend had a little falling out situation which caused us not to like each other or junior yr (2years ago ) soo he insist that he care about him and he wants her to be his bestfriend . Im not having no like i dont like ( there no beef ) i jusy dont like her being my boyfriends bestfriend . And plus i dont trust that bestfriend shit anywaysss !!!! But what are you guys thoughts ? Should i make him drop her ? Is it fair .. I literally told him i will never be with him again if he decides to keep her in his life . And for him to have so much love for this girl is suspicious to me too .. thoughtss ..?

Ps: dont say im childish or anything rude about me . Because i love to get rude back !!!! Fyi !
