Vidya is being so vile

Wow, I can't believe how nasty she is being. I have lost respect character. She went from being sad/hurt to Armaan not getting a family to just being plain nasty and rude towards them. She knows it's hurting their marriage, and she likes that. She purposely gives Rohit/Ruhi more attention to make them more upset. I never saw her go shopping/massage Ruhi before now.

I don't understand how a mother can do that. How can someone be nasty to their own kids for 3+ months, especially when they are being sad and moping around and asking for forgiveness. She truly doesn't care about Armaan and I see that now.
