True there is no excuse of what abir did to mishti, it was so not abir
But the forum members who are justifying his action they are actually not justifying it but decoding it, it is the same abir who when all the proves were against mishti trusted her. Before kunal's truth revealation also when meenu manipulated him with rajgadh adventurous trip of mishti ,he trusted her , he supported her without any proves. It is the same abir who told mishti that she's awesome a day after mishti and kunal's tiff in the mall, the same abir who said ki ladki ki izzat kisi bhi Pooja se badi hoti hai, we all love that abir and that's jab Aaj usne ye Sab kiya we're trying to decode his action because we're not able to believe ki overnight trp ke liye abir ka Pura character hi badal gaya.
He chose kunal, Right he made a choice but was there a choice, agar kunal ko choose nahi karta to kya karta, agar mishti ko bata bhi deta about kunal's truth tab bhi kya ho jaata, kunal ko to sab sach pata hi chal jaata meenu se, and it's not so easy kunal ne bachpan se meenu ko mom and abir ko bhai maana hai ,achanak se after 20 something years he will get to know ki ye Uski real family nahi hai so kya hoga uska mental condition. It's not like mishti already itne bure phase se ladi hai so ab use takleef nahi Milni chahiye And kunal ko Aaj tak takleef nahi Hui hai to ab uski baari.
Abir ko ek galat step ke liye Hum bura Kyu banaye, mishti without saying to anyone without trusting anyone kuhu ki haldi ceremony mein wo step liya, she knew ki abir usse pyaar karta hai, fir bhi, abir ne bhi Aaj ye step liya. They both chose family over each other at a time. But fir bhi they both hoped ki Dusra aayega Uske paas, like Mish on airport or abir in promo (though symbolic)
The chain snatching, push , card phaadna vo Sab brutal tha, I hated that, trp ke liye Ye Sab dukhaane ki koi zarurat nahi thi , to make it dramatic they destroyed the sensitivity of abir, there's no justification for this action and he'll feel guilty throughout his life for that mishti jab vaapas aa jaayegi Uske paas fir bhi.
Mish is the first FL I loved and she's awesome and I always try to decode her action be it haldi or rajgadh drama, and that's what all are doing with abir just trying to decode his action
