As Swapnil is back and Radha does not like him, why doesn't she just leave the Nerulkar parivaar and go on. She does not have to go thru the abuse and tolerate him. She is no way related to him. The Nerulkars will realize her importance after she goes and try to find her.
Why can't she go find a job as a nurse somewhere in a remote clinic or hospital and just leave the mess.
I know it is her own doing, but I feel bad for her. I have not watched the show from the beginning, but I guess she never got the love and affection one gets from their real mother which is why she is the way she is. Just a thought...
