This is not about logic..its about how convincing viewers can get with characterization, writing & execution to be able to connect well.
Why & how did an young unmarried, successful, kind of rich architect/interior designer like Ishika with her influential client base fall for a middle class, not so successful much older man Jayesh having responsibility of two grownup children living in small 2BHK flat, still legally wedded to his wife??
what has she seen in Jayesh, what'll Ishika benefit from this relationship? why was she so desperate to move in with Jayesh in such a middle class society block, rather than making him shift to her own flat? why is she losing her class with street fights? what'll she get in breaking some small FD savings of chitnis family in dubious means by taking over that money?
EMA where other woman is modern plus evil, families broken due to EMA causing turmoils, other woman's obsession for a married man - these are quite common plus cringe plots in Hindi serials, but usually man is also shown in a better position.
So most TV fiction viewers kind of know what will be base of such 'other woman', here Ishika's EMA with Jayesh has no proper base shown to properly convince us.
Agreed!
That Ishika side of the story is odd and I wanna know more about it because it doesn't make sense.
I can only relate to Amu and her Mother at this point, minus some parts that could be better their characters are great enough bakhi okay hai and waiting to see some improvement

Thankfully, Bhavani and kids have moved out of the place ... else they love to have all three in the same home. Probably have a little more budget to afford another set.
it's difficult to watch, empathise, identify with the characters when everything is so dramatic. I am skipping half the episodes unfortunately. It's also difficult to give an honest review when the tracks aren't given time to pan out, and there always has to be blame game, insult and drama. Not done. 
If it is.
Like Amu search for clues and find out about the BIL spiking her drink and when she blames him, they won't believe and insult her. because of Nimrit rishta.
