I don't think the CVs are taking the route of showing simple insecurity.I think they are moving the track towards a mental disorder. Ishwari's obsession is increasing every passing day. The only people who could have come between Dev and Ishwari earlier,were his sisters and Ishwari controlled that aspect from the beginning so the situation never came up.
Pre-marriage, Ishwari used to feel guilty if she spoke rudely to Sonakshi and made her upset. If you noticed, today when she saw Sonakshi happy after Dev left, she yelled at her, was rude to her and that made her feel better, that she could take the smile off Sonakshi's face.When that was done, she immediately masked her rudeness as concern and was back to sweet innocent lady. But even then her obsession was present, just masked.Sona's only identity for Ishwari is in terms of Dev.Dev's wife(read toy/zid here).A choice that should not be questioned.
Every small change makes her agitated. The comment to Sona about her sleep was because Dev went to wake her up with breakfast.Dev changed a ritual that existed between Ishwari and Dev because of Sona.She wasn't just sad due to the sudden change, she was irritated, she was angry at Sona for causing that change.
The gift scene?For Ishwari, it was as if her identity and her rights are being snatched from her.Sona wasn't supposed to become family for Ishwari.She was supposed to be an object.Dev's affection wasn't supposed to continue, he was supposed to get back to normal as if nothing had changed.Why?Ishwari always saw Sona as a zid of Dev.A temporary phase.And now that she is seeing changes happening, observing Dev giving importance to someone other than her,she is thinking(subconsciously) that Sona might take her place.
She doesn't understand the concept of 2 different relationships right now.All she believes is that if Sona's value in Dev's life increases then her would automatically reduce.
Cupboard keys- Those keys are a form of control over Dev's life for Ishwari.She won't hand that over to Sona because she doesn't want to give that conrol or right to her.What she fails to understand is that the right is already Sona's (with or without keys)
The consummation or intimacy - Ishwari feels like Sona can provide Dev with something that she can't in this aspect and that would lead to Sona gaining importance over her.So how does she ensure she remains at top? Create situations to make intimacy impossible.As long as possible, in any way possible.Noticed the relief on her face when Dev agreed to drop DB? Relieved because once again she stopped Sona from doing something that will make Dev closer to her
We all feel that Ishwari can't stoop lower, can't be creepier or more disturbing, but I think in coming episodes we'll see just that. Ishwari was never able to raise all her kids equally because she herself was not emotionally stable due to all that she had to go through.
I know some might say that these kinds of mothers exist and it's insecurity at an extreme level .But I think there are times when we don't recognise the signs of mental disorders because it is not something openly discussed or addressed(at least in India).There might be cases where MILs do change, there might be cases where the MIL and DIL learn to co-exist even if there is no acceptance or love, but there are also cases where the marriages end in divorce, where the couples end up living away from parents and may be that's where, some of those cases remain hidden and unaddressed.
That's just my POV.May be the CVs don't take that route.But going by her behaviour ,that's what I feel.In the end, she will become a good MIL but the route taken to reach there will differ.
Do share your thoughts.
Update: Read about Borderline Personality Disorder.
Disturbed sense of identity,frantic efforts to avoid real or imagined abandonment,impulsive behavior,self harm etc.
If you read about it you'll feel like you are actually reading about Ishwari.Thanks for suggesting it Tia.I think you really found the exact cause.
