like I said emotions don't work that way.Ragini is supposed nay expected to look at the situation logically even though we excuse Sadhanas behaviour as an emotional outburst.
Wouldn' Ragini have an emotional response to her younger sister hitting her husband,she is human after all.
There are going o be no winners in this situation only losers
Ragini has to swallow this bitter pill if she wants peace in the family. Sadi did apologize to Ranveer so Ragini should also forgive her and not take it to heart. Like I said earlier, Ranveer's life was also in danger with this act so Ragini should try to understand Sadi's reaction.
