this post pretty much sums it up from a user on reddit today:
I feel teja isnt insecure (or less insecure) about her relationship per se. She is actually massively insecure from the strong women around her. She just masks it up as being insecure abt her relationship so that its more palatable/acceptable. This way it comes off as just the 'jealous gf' or 'look-how-real-her-love-is', and doesnt highlight her insecurity/game. She is very insecure abt any strong women personality who doesnt support her (Shamita, Rashmi, Donal). She wants to be the ONLY strong, 'woke' woman in the house. This was very evident in the devo-bichukle spat.
Also, the fake cuteness she shows (complete with the makeup with blush on the nose), probably to portray shes the complete package, is yuck š¤®
This girl is problematic af.
In summary:
Teja was jealous of Donal too from day one when she noticed how pretty and cute she was..Donal used to get a lot of attention from KK. Then she began targetting Shamita, even Rashmi.. who is actually her bestie from outside.
She's scared of being one-upped/replaced by anybody. Her insecurity doesn't stem from the relationship she's in. It stems from the fact that she can't take it if someone is better than her. š Teja actually said it to Shamita while apologizing. "Aap itne sundar ho, main insecure houngi hi na š„ŗš¤š»" I think she wasn't lying tbh, lol.
