Regarding IMLIE, I completely reject the idea that this character is unrealistic. People like this exist actually who are self-sacrificing, who are brilliant. Moreover who decides what's realistic or unrealistic? It's a subjective term so I don't understand why a character should be blamed for not upholding someone else's definition of "realistic". I think the one person who suffered the most in this situation is everything. She had to leave behind everything, face mistreatment from AC and even Adi initially. She went through all this for nothing, she deserves better.

Regarding ADI, I inherently dislike him for his flaws and I agree he's an anti-hero. He's a grey character who is selfish, sometimes manipulative too also quite callous. Despite recognising all his flaws, the audience including me still loves Adilie together, which I know isn't okay from set standards of morality. I think despite being so flawed Ad actually cares about Imlie and connects with her simplicity, ambition and her strength of character.
The marriage with Malini was the worst mistake of Aditya. Only and only Aditya. If only he didn't be selfish in that moment and spoke up.
Adi's equation with Malini is flawed, always has been so apparent from a lot of conversations and scenes which talked about their past. You can call this a bias but I think Adini would have broken up even without Imlie, they don't match. Adi looks for fierceness which he doesn't find in Malini (unfair comparison I know)
~~~~~~~~
Regarding MALINI, I will tell you outright I dislike her but not for the reasons you think. Malini is completely innocent in the wedding drama, she thought she was marrying the man who loved her(or it appeared so). Keep Imlie aside, what I gauze from all the scenes describing past is that Adi is a practical guy who didn't think about love at all, his family was pressuring him to marry someone. Malini was his good friend and he thought understanding is the key to a relationship. This is exactly what happens in real life with arranged marriages, people marry literal strangers even educated ones. Only difference here is, Malini loved Adi but Adi didn't. He just thought Malini will be suitable for him.
Her experienced real love with Imlie, no matter how wrong someone thinks the conditions were. But yes, Malini no matter she's like doesn't deserve this at all. She deserves a man who would love her that is why I want her to leave Adi.
Now regarding why I don't like Malini, (this is all independent from me liking Adilie) she's very classist. She concealed it really well because she has always been image concious. Also because Aditya likes people who are simplistic and have strong values (quite ironic I know). Imlie has been Malini's pet project. Now you would say I'm accusing her, no.
Malini never actually cared about Imlie. You must've heard white people like blacks only as victims but the moment they try to be at par with them, their superiority comes out in front. This is exactly what happened here. Malini claimed she didn't believe in class etc but the she used Imlie to vent her frustration, was jealous because she thought Adi cared for her. Mind you here she didn't know the truth but still she chose to insult Imlie for that sindoor and call her naukrani, random ladki etc. And this is just one instance.
Malini is also very manipulative. She says what she wants and then goes like koi nahi nothing happened. Maybe you haven't met manipulative people irl but that's how they behave. It's called love-bombing.
Finally, I dislike Malini but I don't think she deserved what happened to her with the marriage/troubled marriage. She didn't deserve that no girl deserves it no matter how flawed. The only logical solution is that Malini gathers her self respect and choose herself over Adi. Also if Adilie want to be together, I don't think anybody can stop them at all. Also, as an audience I would want a bright future for Imlie and Adi finally being free from all the guilt.
