I don't know what Damini's problems is. Her charcater sketch post leap is very confusing. Tripti called her Husband Gautam, Karan ki dum. Still Damini supports Sahil and his family. I think it is her own selfishness towards Nakul which has come in the way. Then she should take the custody of Nakul back rather than give confusing signals about her behaviour. She didn't even stop to meet Ganga. Atrocious lady this Damini is.
The saying goes the weak support the weak, while the strong get on one side. And the weak always crib against the bold and the strong simply because they can't match up to their level.
If Damini has done nothing extradordinary in her life, at least she should not try to create further friction in the house. 😕
