Well, I don't think that's the case now. He did support Sah during the jail track when every single person was against her except Veer maybe.. .. And also Sahiba hid his fathers truth from him, gave zero emotional support, kept ranting simran, blamed him during his weakest times (well, Angad has done the same with Sah too) .. Soo.. But even then he went to her college supported her...
And today I really liked how Angad clapped back at Seerat. He was quite clear with his words today.. He asked her to back off.. His dialogues were crystal clear... But again she started manipulating him(+extra glorification from the makers with all that BGM, even then I didn't feel an ounce of empathy for her) he felt bad.. Bcoz he obviously has a soft corner for her.. Probably bcoz she's his first love Or something I djnno... But he didn't have to pick her up from. That drunken fiasco.. He cud have called Veer or something.. He's wrong there.. But otherwise it is clear from the episode that Angad is least interested in Seerat.
I will wait for this whole Manveer kidnap thing. If he believes that she couldn't do it even if she claims she did to shield Manveer, I will see some substantial progress from his side.
Else it is just him and big words that he takes only a second to forget when it comes to Sahiba, with Seerat of course he loves to forget everything and give 50 fresh starts because ph ka bhabi worship hi theme hai.
