And that's the point. She believed Kairav can never hurt anyone even when all proofs were against him, and Kairav, has gone through this trauma twice, when he was blamed for pushing someone because of circumstances. Akshara truly believes she is completely blameless in what happened to Neil, whether right or wrong isn't the point, and hence, she apparently still has trauma with being blamed for his and Sirat's death, so for people who have gone through this twice, and then hated the people who blamed them (Kairav even hated his own mother), it won't make sense if they believe with their eyes closed, no matter who the blame is being pointed to. And if they do, then they need to be accepting of the "negative" tag because even though they went through the same, they didn't learn even empathy, forget sympathy.
I said it should happen that ways because else it shows no growth for the brother and sister, and without that growth, it makes no sense for Abhimanyu to even keep a relationship with anyone in Goenkas except his 2 kids. Mahaan FL needs to mean a growing FL. I didn't find any flaw in her moving on with Abhinav, I found and still find flaw in the way they both made sure Abhimanyu is wiped from Abhir's life, even if he wins.
