Hi!
Well to answer your question-No I dont think sid is insecure!!
When he said he wanted ridhimma back he said it in a very happy manner- not in a sad and depressed way which shows that he had no malice in his thoughts at all!! Plus I feel when he said that, he meant having ridhimma back to work with him too!
And the reason he was looking for girls for arman is because he wants to see him happy just like he is with ridhimma! He got the idea from shilpa and thought it was a brilliant way to take his big brother out of his current misery!! I dont think that shows any selfish motive! In fact it is concern for his best friend!
to be fair, perhaps sid might feel a little uneasy at the thought of arman and ridhimma working together, but isnt that a natural emotion?? After all arman is his wifes ex-boyfriend!
Anyway, I am under no illusions that any of the AR fans wil agree with me but I just wanted to answer your post!😃
