okay so get this me and this girl we will call her apple had a friend break up right. mind you I introduced this girl to her bf which we will call orange so orange texted me saying apple feels bad and that everyone she gets attached too leaves she said me for example??? I go in confront her because she said she was done with me and that she’s tired of being around people who don’t gaf about her so I unadded her on everything because we’re not friends? anywho I confront her she’s like oh it’s not why u did that blah blah blah and I didn’t leave her it WAS LITERALLY HER and now this guy umm blueberry I was asking him about this girl strawberry cs she hasn’t been online but hold the phone right there me and blueberry hate eachother so he get to calling me a bitch and telling him to get off my line and he gets to saying you left my sister which is aka apple mind you I didn’t want orange to know why we stopped being friends he always wanna be in smb business now blueberry is saying oh I left apple but main question is why tf is apple running her mouth to everybody?? so is my “bestfriend” a bitch?
