I seriously doubt if imlie loves Aditya or her thought process was such that she must love her husband.At first she was like an empty book as she didn't like anyone or focus on anything apart from her studies.So when she got married for the first time it was easy for Aditya to weave his place in her heart.Because even though imlie is irritating at times ,how could she forgive her husband who slept with Malini or her in-laws who humiliated her? Even though she took a stand for herself and left the house ,she could not bring herself to sign the divorce papers or she did not even think that such a thing could happen.She was opposing marriage with Aryan because now the empty book is marked.If she respects the institution of marriage then Aparna or anybody else cannot separate her from Aryan.And I feel she is not a person who can ignore her suhag easily and betray her husband.
Only rupi and Sundar are the sensible character in Tripathi's house.If imlie has lot of self respect then why did she accept the house on her name or let Tripathi's stay there?She could forgive the whole Tripathi family but if anyone gives her respect she takes them for granted (like her Amma,Aryan,narmada,Arpita).Today Imli thought only about herself and not about the consequences of leaving asr who supported her in hard times.
