Ajeet is perfectly reasonable in hilding Andgad responsible. Seerat par bhi gussa hai but for him Sahiba is dead and the one who killed her is Angad because he wants to marry Seerat. So his primary focus is to make Angad get punishment.
Eventually we know he's gonna apologize when Sahiba comes back and says Angad neh mujhe bachaya. Mongas will say sorry and brars will start attacking Sahiba saying usie vajah seh Angad musibat mein tha. 🙄
Sahiba is to blame for giving a chance to Romi without even getting a restraining order against him or informing police also. But then again, Angad agreed with her and let him off too.
Seerat ke case mein Sahiba never gave Seerat a clean chit but she blamed Gary also for pretending to love Seerat and leading her along and as a sister she felt bad to see Seerat suicidal. So she forgave her. It wasnt Sahiba who encouraged Gary Seerat wedding, it was Angad. Sahiba warned that Gary cannot be trusted and wanted to help Seerat be independent and work but Seerat didn't want to do anything useful in life. Even after Gary death, sahiba told Seerat to get a change of scene, go home to mongas, start working etc but Seerat didn't listen and Angad is the one who kept interfering and making sure Seerat would be near him. He believed that she was grieving death of her abusive husband even though she was least affected by him leaving brar house and instead had been clinging to him and proposing EMA. Instead of realizing that after becoming widow she'd become more clingy, he was running to offer kandha and feed her haath seh despite SO many people available to take care of Seerat. Seerats antics have been encouraged by Angad and this despite Sahiba warning him more than once and Seerats brazen behavior.
Even now he's more upset with Manbeer than Seerat. How did manbeer get the idea of his marriage to Seerat?! Its because she thinks he's over friendly with her and sees them as being "couple like" in their behavior with each other. Seerat exercises haq over him, speaks for him and he lets her do so. So as mother she thinks he still loves Seerat. If his pyaari mumma also thinks he loves Seerat, not Sahiba then why should Sahiba trust him?
Pyaar karta toh Seerat ko get lost karvaata. Pyaar karta toh Sahiba ko secure feel karvaata.
Sahibas concerns were treated by him with callousness. He calls her issues as her "veham". Is it veham when Sahiba sees Seerat in same gown that Angad gave her, sitting in car front seat, touching him, going as +1 to events, sees Seerat redecorate his room, hears about ILU, sees Angad confess to Seerat too, sees marriage proposal of Seergaf being publicly announced in front of her?!
Out of all these straight line propsal is the only thing Sahiba knows but Angad doesn't know. But if you ignore that Angad has done WAY too much to make Sahiba feel insecure, hurt her and therefore theres no way Sahiba can trust him.
Still part of Sahiba is waiting, hoping thet Angad will explain and sort it out because she now loves him. But everyday her hopes are crushed because something new happens to make her feel worse.
When Romi matter mein Angad acted, she felt like maybe he does care, maybe there really was a MU but she comes home and sees Seerat has changed their room to be as per HER preference and Manbeer is announcing shaadi and Angad NOT saying much except asking to speak to Manbeer alone. In front of Sahiba while she was there he didn't do much - he could simply interrupt and say NO I don't want to marry Seerat. But he said everything except that.
