In my opinion the biggest difference between these two relationship is that Gaushal show there liking for each other... again they "like" each other i didn't say they "love" each other... They both always support each other and stand up for each other... Gauhar left the show for him (yes she came back for whatever reason) but at the very moment she supported him...
Kaushal fought with andy for Gauhar... (Again i am not saying this is right but just pointing out the incidents were they supported each other)...
On the other hand with Tanman's relationship its always Tanisha who supports Armaan... She is very loyal to him no matter what... but Armaan doesn't give a dam.. He had never stood up for Tanisha, not even as a friend let alone an admirer, lover...
The only reason everyone is disliking Tanisha (for those who dislike her) is because of the way she behaves when it comes to Armaan... I think if Armaan also behaves thesame way and stand up for Tanisha like the way she does for him, then it would be more understandable and acceptable... i don't know if i am able to express my views properly right now... 😆
There is no doubt Tanisha is being portrayed as a doormat right now... So if Kushal warns her then i think its a good thing for Tanisha... I haven't seen the episode for today but i saw a sneek peak where Tanisha voted for Andy and Armaan voted for Sophia... I was so happy to see that because Tanisha decided for herself and was not influenced by Armaan this time.. which is exactly what viewers wants to see...
