I agree..I feel the article might be wrong..
For divorce to take place both have to fight with each,
there might be lots of MUs ..but it is highly unlikely for SINAL to opt for divorce
to back my point , i want to mention few incidences
1.Before marriage , during SINAL confrontation , it was Kunal shouting yelling on Sidhi, being rude to her but sidhi never reacted giving respect to their relation and his age.. so only one sided
2.After marriage, early days , first few months..again Kuanl doubted sidhi, thought she is lying to him. has stolen the Cd , b, he shouted , yelled on her but she again was quite..
she spoke .like in Karwa chauth, she gave him his piece of mind once he had calmed down..so no fights again..and even between all these they never thought about separating from each other..
3.Later phase of marriage...before c-night, primarily during Raveena's wedding they were occassion when Sidhi erupted , was angry on him and kunal for a change was calm, he never gave back to her, listebed to her and even did what she wanted him to do..afaon one sided fight and no chance of opting for divorce..
4 After c-night , before confession..Even after registering for divorce , Kunal and sidhi exerted right on each other esp Kunal, supported and stood by each other, cared for each other..it was like the divorce thing was never in their mind..not only SINAL after certain scenes like the holi one or the kidnapping one, even we forgot that they had opted for divorce..these phase brought then even closer to each..divorce not possible..
5.after confession till now , they are so passionately and madly in love with each other that even if they fight, there are MU i, they might not talk to each other for a while but will never think abour divorce
6.only time they both argued and fought with each(excluding their nok-jhok) is during the fake pregnancy scene and even then sidhi shed few tears and Kunal completely melted and forgot everything..
so keeping all this and their basic nature and character in mind, don't think they will opt for divorce however angry they might be on each other.
