Yes we all do drool and admire a married actor or celebrity, but making him our obsession doesn't happen in 99% cases. Whatever Teni does or did with Parth has been pure obsession of hers. She tried to make him do things for her like an obsessed lover would. She used the baby in her womb as a weapon many times, since she knows it's the weakness of Parth. She developing feelings for him and acting upon them are two different things. If people can't understand the difference between fascination and obsession, then I can only pity them!
And again Shorvari is blamed entirely. Teni is acting upon Shorvari's orders is downright lie. If she doesn't wanna do things no one can force her to. Remember the time when she accepted to Aman's wedding proposal and how PaRi were trying to convince her against it? She threw accusations at Shorvari at that time too to justify herself and said if shorvari can seduce and marry Parth for his riches why can't I do it with aman, vaghera vaghera... Even though they tried their best to make her see sense, she never understood their point unless she started to feel that she's not interested in marrying nor attracted to Aman. Similarly if she had set her heart against the situation here or on Parth exactly,, Shorvari's words would not have any impact on her. She won't be doing any damn thing on her orders. Can never accept she's doing all this only on shorvari's orders without any selfish motive. It's definitely not true.
