Okay so i just wanna rant and need opinion in this situation with my "friend" now ex friend.

So this gurl had been my childhood friend for like 14 years now. 2 years ago, i left my previous institution where she stayed and still studying. Now there for the very first years things were fine, we were "best friends" and there was this other girl in our class and our coaching abt who she used to bitch. Now in current scenario this "friend" is now "best friends" with the girl she used to bitch abt hanging out with her n shit but when she is pissed off she comes to me to talk shit abt her. Now i am not bothered abt this atm. 2 days ago, it was my bday where she pissed me off to the core. After we reached the restaurant within 40 mins, she went like "whag are you doing" "jaldii karo" "kya time paas kar rahi" "time nahi hai" and i am telling you she had to do nothing. Her parents didn't even call us once asking abt her or how much time it will all take but this bitch was so desperate. Now after payment n everything, i was getting my pictures clicked by my bsf while waiting for my dad to pick us up. Now this bitch literally shouted at me being like "kya kar rahi ho tum" "hume late horha hai" "hum chale jaate hain khud se hi fir" Man i cannot even tell you how my heart dropped and my mood got ruined. My bsf hugged me being like "its okay" "i will click your pics" but yep my mood was ruined. She repeated this in whole 2 hours we were there at the restaurant. Now today's scenario, we study in the same coaching so i msged her and asked "aaj coaching hai?" Her reply: "hm" i asked her "kitne baje?" Her: "5 baje" and this bitch. Obv i went there and guess what? The teacher wasn't there. There was no coaching for today. And she lied to me. I am fuming with anger and just wanna go to her house and slap the bitch outta her. What do you think i should do? Should i remind her of how much "ahsaan" i did to her? Or just slap her once i meet her?
