I agree with you but partially!
The thing is, that Ankita loves Naren, immensely, unconditionally and irrevocably, and just as they say, "Love makes you do crazy things, insane things, things in a million years you'd never see yourself do. But there, you are doing!"
Ankita needs self respect in Rushali's case, I completely agree but when it comes to Naren, she can't possibly think of causing him any harm, neither she'll let anything or anyone hurt him. Her love for Naren is so strong that she is able to face any situation.
And by not arguing against Naren, well isn't she emotionally manipulated by Rushali? That don't force Naren into something, let him be happy with Pari and stuff!
Love makes a person do such things, Ankita can do anything for Naren and she proved it time to time. It's just little bit weird and crazy to understand. But Naren has disappointed me and so has Pari.
I mean just a day back, she was saying that she can't compete against Ankita's love for Naren, what happened now.
Well, let's see what happens next.
