What does the new montage mean?

I just saw the new montage, Ankita is ALONE and in a white sari (which one wears when grieving in Hinduism right?)...and she has aarti or something in her hand (sorry I'm not Hindu so I'm not sure)...what does this new montage mean? Why is Ankita alone? Is Naren going to leave her? Does she wear a white sari because she becomes single? Aren't white clothes worn when someone dies? I'm just so confused...can anyone help me understand the montage?

that's jst for new time slot I guess😊
