Everything about this show has proven that Kunal is the worst
1) gives lectures about loving and respecting your wife only to prove he's the best person and then cheats and dumps his own wife same way - then when a friend praises him for saving his marriage he doesn't even feel bad for living a fake life or confess his own mistakes he's just worried about getting caught with nandini
2) chased a vulnerable and traumatized woman who needed time to deal with her trauma not a new man
3) started an affair with nandini without even trying to break things off with mauli first (wanted to see it was something real before he left his 'perfect' life)
4) didn't even treat mauli like a human being after he decided he wanted to be nandini
post leap
5) physically abusive with mauli when he found out about mishti being his bio daughter (pushed her against the wall and screamed at her) even though he was the one who repeatedly said he didn't want to be mauli
6) tries to manipulate mauli into moving on with ishaan by kicking her out of the house in the middle of the night and separating her for her child to make her vulnerable (REMEMBER nandini was also a single woman with no family when mauli took her in he knew what he was doing he knew this was a good time to start a relationship with a woman, thank god mauli and ishaan didn't fall for it)
7) still isn't treating mauli like her own person trying to make her decisions for her. mauli-radhika-dadi were a family, mauli chose them over ishaan is a reasonable thing to do but he couldn't understand that and took it upon his own hands to change her life
memory loss - even before nandini MauNal had problems
7) Kunal pushing her to be more feminine, getting mad that she gives more importance to work than him, still tries to be intimate with mauli even though she's clearly feeling uncomfortable, talking to strangers about their family planning
8) when he hears that one recording of Nandini asking Mauli to adopt Pari he loses it and calls her a bad person without even waiting to hear the whole story
9)tries to forbid Mauli from seeing Ishaan-Pari-Misthi
9) when people told Mauli Kunal was cheating she chose to trust him, she didn't even open Rajdeep's message, she felt guilty for even doubting him a little bit but Kunal's first reaction?? Put into his mother and grandmother's head that Mauli is going to betray him, he stalks her and only after he finds out nothing happened he feels bad, he thinks mauli doesn't love him but as soon as he sees a gift he thinks everything is fine between them because that's all love is to him gifts and sex
10) when the clinic calls the house to ask about mauli he starts doubting her instead of being concerned that his wife left for work at night and never arrived and her phone is switched off shouldn't he be concerned for her safety?
11) in the precap he finds the romantic note to ishaan and he's angry, he's not as distressed as mauli was because he feels entitled to mauli's love because of his good guy persona, not because he genuinely wants to be with her
