In the precap he did not react infact he ask Pari to leave them alone so they can talk
Methinks she'll say yes hoping for some kind of reaction from her "jeeju", but instead he'll be eagerly waiting for the day she leaves BH... so Niti will have to pull a last min stunt to stop the wedding.
Right now, she knew she was under Taiji's scan who's watching her very attentively.
So, to escape her interrogation and more proposals she said yes, I guess (esp. since the guy is indeed Niti's type aand from a good family).
Basically... she nor Pari could make any excuses and the way asked for her hand in marriage was so 
.
Anyways, I'm getting too sick of the show being all abt Niti... P/R just got married: let the couple have some alone time instead of showing her attached at the hip w Niti.
As for Rajiv, even during Shelly's monologue he didn't react much.
He doesn't seem to care. LOL

Ab toh sirf SR karab ki hai Neeti ne. If she stays around, Rajeev and Pari ko kabhi akela nahi chodegi yeh.
And it's absolutely true that she hasn't lost her memory at all and I am sure Taiji's suspicion will be proven right one day.
