Astha and Sid's relation seems to be disgusting as well. By encouraging Sid and Astha's relationship
I don't think any normal parents would approve of their child achieving love forcefully in life. Like, come to think of it Sid has NEVER told Simran or anyone else for the fact that he loves, or even likes Astha in that manner! Another thing there's a huge age difference between Astha and Sid. Astha's like 18 and Sid must be around (28)! When Sia was born Sid was atleast 8 years old, Astha's two years younger than Sia, so that makes her 10 years younger than him, doesn't it?
Another, thing I do believe that both Simran and Abhi are mostly responsible for Neha's death like Radha Jee believes it to be. Come to think of it Simran didn't really leave Abhi and Neha alone after they were married. It was like Abhi was just married to Neha for the sake of "obeying Simran's wishes". Neha's jealousy and insecurity were justified. Would you like your husband to come back from US and head right to their ex? (Without even coming home). Neha on her part did do all she could to make Abhi happy, she tried to accept Abhi's "Relationship" with Simran, loved the real Astha for Abhi.. All these major stress issues can indeed lead to the situation that Neha faced. Simran kind of ruined Neha's life by asking Abhi to marry her, and then by being a third wheel. If only she hadn't forced Abhi to marry her, Neha would be sad for a while but then she'd get over it. She could have married someone else and may well still be alive.
