So I think Geet does love Prem but at the same time, she knows there is something between Prem and Heer and she's doing all this to convince Heer that Heer still loves Prem. She's trying to get Heer's feelings out. Now why else would she "drag" Heer to Ludhiana? If she loves Prem so much, won't she want to spend quality time with him alone? Why does she drag Heer with her on every single "date" of hers? I know they are best friends but believe me, I don't drag my best friends to my dates no matter how much I love them. 😆 Also what's with her keep saying "You act like your his wife" and than again, wait for Heer giving her an evil look (which is quite obvious that Heer is indeed Prem's wife) for her to say "I mean, blah blah."
And by any chance she didn't know, today Heer's reactions should have proved it. Like why would Heer be crying her heart out when Geet was telling her that Prem still loves his first wife? Why should that make Heer cry so much if there was no relationship between Prem and Heer?
