She should let the courts decide on the fate of Vidya or come to a sane agreement with Ahem. Have the kids during the school days, let him have them on weekends/vacations or such. She should further grow into a strong, independent person who owes no one anything. Vidya should learn the fact that she has a loving mother and father even if they do not stay with each other.
Meera should join them. Radha can remain and serve Koki and Ahem in MM. Rashi can have her parties and guests while Radha can remain whatever she wants to remain for. As for Ahem being in love with Gopi, it should not matter.
There are times when you love someone but cannot live with them. It happens. Gopi and Ahem are adults. If Ahem finds Gopi so unpalatable, he should have the guts to ask for a divorce and Gopi should oblige. No use having cold feet. He either wants Gopi or he does not. He cannot have it both ways.
Ahem and Koki are not objects to fix. They have to change themselves. No one needs to pamper and serve them for a change of heart. That's been done before and see what happened..
As Koki said, she will take her hate for Gopi to her grave because she cannot forgive Gopi.. Fair enough. But don't expect her to stay and take that hate everyday because she was in an accident 8 years ago and managed to survive thereafter.
Why cannot this be a story of how Gopi became her own savior? Why cannot she show the woman watching that goodness can also be done by not bowing down to abuse but to hold your head high and walk away with dignity?
