Another phase of lie..

Simar should have told the truth to prem yesterday itself..i mean, doesn't she feel guilty of the fact that proving the innocence via letter is temporary and will be gone away the instant prem gets to know the full truth of the marriage..! Yesterday was the start of another phase of lie on simar's part and guess, another 2-3 months of wait for the truth to come out.. and the speed of the show is v v slow..don't get to see anything interesting to look forward to in an episode

can u tell me what was in the letter?
