theres absolutely zero regret or realization from him. what did he expect from Sahiba after she saw him prioritize Seerat and propose to her in front of her eyes. And why wouldnt she divorce him?! also he heard about the way manbeer behaved. but he just needs an excuse to blame Sahiba. he has nothing to say to his mom and he is back to letting Seerat parade around . he wont even listen to Sahiba, just keeps on using her as a punching bag and then expects her to be unaffected. love toh door ki baat hai, he doesnt have basic decency about how to behave with his wife in a public place or in front of his family. he doesnt care about her hurt, her pain, her insecurities. all he cares about is his own image. itnaa kuch karne ke baad family ignores that there were many moments Angad had with Seerat which impacted Sahiba and are holding only Sahiba accountable. bebe who herself was uncomfortable with Seerat-Angad in that event has conveniently forgotten it and is back to Sahiba blame.
This is going the same way as their other plots. make a strong FL become lonely, compromise on her self respect to accomodate a man who she thinks despite all his flaws does love and care for her but will find out its all a farce.
