There should not be any opened issues between husband and wife. What Ishita did was right in a wrong way because changing name definitely create doubts in mind . They both were wrong they both were right.
It's about a couple to take there relation to any level. Ishita and Raman needs to talk. She should know what is bothering him. If you remember Amma's accident case .. Raman was the first one who came (after fire scene ) and asked her to say some thing then she said ' you ar living to me, hiding stuffs from me, secret meetings are going on' ' I couldn't understand anything , you tell me , clear my thoughts' and he only said ' you have to believe me , I am not doing anything wrong, what you saw is not the whole truth' . That is called a matured stand from a hubby's side as he wants to value this marriage.
Why can't now Ishita took the first step to ask what is bothering him or if he can't spell that time and now she knows because of Mani he is insecure ' what can't she said ' You have. To trust me.' This is not about trusing anymore ... So she has to give him some hope to hold on I am not wrong , don't give the full explain action if you don't want and want him to search by his own But you sure can give him Hope to look beyond...
Being a women I could do this, as for me I value my relation and wants to protect it. The way he reacted was totally wrong and he has to apologize for everything but still he deserves a hope from his wife to hold on the ground.
