"achay dost" gaslighting me?

hello. i will keep things short. mein khud doodh ka dhula nahi but tell me if im wrong here. bhaio jesa aik purana dost tha/hai, kuch time se badla badla hua especially uni ake, jabse wanna be cools k sath utne bethne laga. mazak aur baton mey mostly taunt and belittle karta jab tk mein uski baton se agree na krun. jab tk mein han mey han milata tou mein acha tha. ego bohat hai agle mey ab. fazul ka mind fuck aur kela khana even if i go out with my other friends, or technically doing anything without him. parasitic behavior. felt like from most trusted and acha bhai aik energy draining dost ban gaya, choti choti baton mey ch##yape. and aur kisi apne dost k sath mil k corner karna to make me feel guilty. so, went outside to eat, with university fellows yesterday, sudden plan tha bec aik ki birthday thi, i didnt know, mei uski khushi mey shamil hona chaahta tha wrna im dont even talk with them much, i told my friend yeh scene, muh ban gaya uska(even tho my classmates asked him to come too). i came back home told him k sorry it was important they kept insisting(even i offered him k you take my bike home tumhe asani hogi i will manage) (and unusually don't hangout like this, either im with close friends or all alone nature hi aesi). he started of with jokes k khane k peechay chor k janay walo mey say ho, this and that, even k "hum bhi aesy kam krty hain likin itne ga##u nahi hain k khane k peechy chor jain", i clearly couldn't tolerate the bullshit. end mey kehta mazak tha tu meri tou wo intention hi nahi thi (clearly when i said mujhe yeh baat buri and and teri mein dil se izzat karta aesi batain na kar to which he kept saying i dont give a fuck, i dont care) mood fucked uske bad se kiun k bohat bakwas ki agle bande ne even when i kept saying teri mei bari izzat karta aesi baat na kar.

all this to make me feel guilty bc i left him like this, but another fact that they always keep me waiting in university when they're with their apparent "female friends". i cant tolerate shit like this, sabko self-respect pyari hoti. am i in the wrong. im concerned bc mujhy tou fark parta tha uss bande se. i simply cared but im short ab qadar nahi rahi thi. like agka banda muh pe ghatiya tone mey bolay IDGAF, IDC, aur sab kuch kar k bolay meri tou mazak ki niyat thi. MOST IMPORTANTLY, i was blamed bc he said "meri yeh intention nahi thi ghalti teri hai k tuny aesa socha k mei yeh sab krrha"😂😭

TL;DR: old good friend turned toxic doesn't value anymore, batain aur harkatain aur. claims k tum aik jagah baki sab aik jagah, yet still when im doing something on my own they get furious. all good scenes when im dependant on them or with them all the time.

kya krna chahiye aesy chay logon ka.
