I know all are frustrated so I am trying to be optimistic by viewing another perspective.
I am just trying, I don't know if I will even make sense.
1. Moving on takes some time irl, may be I guess may be the writers wanted to show that but the execution is pathetic if it is so.
2. Whether it's 1st love, an ex or a deep crush mistaken as love, even after moving on a part of that remains in some corner of us. It's does not mean we have not move on but if those moments were real for us it remains thora saa and they do effect us in some way and mostly it's in a negative way, esp if it is betrayal and broken trust, may be the writers wanted to express this but they are doing a bad job at it, if it is so.
3. From one of MH's honeymoon prabachan , where she said MA's past will always remain a part of him, may be the writers wanted to show the acceptance of the past instead of showing denial as MA is in like, koi fark nahi parta etc. We usually move on when we accept our past instead of just pushing our thoughts away.
4. And we humans are faulty, our thoughts are many times corrupted but it is ethics most of the times which stops us, and that differentiate us from cheaters.
5. I don't know what to say about Babita though. I guess dictionary can instead define the meaning of superficial - to be like the class of Babita. Masoom is actually better than her, itna two-faced v nahi hai I guess, she at least has a selfish reason. But it feels Babita gets sadist pleasure in torturing her Bahus.
However I wish if MA is shown so faulty, so they should also show MH same way. By showing one so good and another faulty, they are making all of us wish MH moves on with someone better. She would have been so happy without the Alahawats unnecessary drama.
This was only an attempt to be optimistic in this current frustrated scenario. I guess jaldi sab thik ho jaye, warna I guess they will lose most viewers.
