Even if AD is shown to be staring at Durga , dreaming about her what he feels is attraction not love. May be she is the first woman in contact with him so closely whom he doesn't consider sister,mother or bhabhi. She was his enemies wife thats why he didn't adopt her as sister like other three clones. Then she remindedd him of his past 7 he strted noticing her other than just a weapon. And he was smitten by her looks. Durga is his creation may be based on his past. So yes all this made him get attracted to Durga pushed by MIL. not Bani, he doesnit know Bani.He doesn't think of Bani or Durga as a person & is not impressed by her vitues.In fact he doesn't like when she shows any human feelings & told her to stop using her heart.
Jai is totally different. He has always seen Bani as the person she is than a beaytiful lady/girl.Even at their first meeting he noticed spark in her eyes & saw what she is made of. After their forced marriage he slowly fell in love with Bani who card for relations, morals, haad a big heart, still was strong & detrmined. It was her inner beuty that he fell in love with & not te outer one.That he started complementing after Dubai thats way later from the time he fell for her.
What I think is Jai's love is true love & what AD feels is attraction for Durga.
