Jagya has accepted Sanchi's proposal and surprised many around including Shiv who initially thought Jagya will not accept this rishta. Now that Jagya is ready to marry Sanchi let's see why Shiv shouldn't have accepted this rishta way before when sanchi confessed her love for Jagya.
AVOID AWKWARD MOMENTS BECAUSE OF THE PAST: Jagya is Anandi's ex husband and Anandi is married to Shiv so now after Jagya and Sanchi's marriage it will be a very awkward situation for Jagya, Anandi and Shiv as their relationships will change and Jagya will become Shiv's brother in law.
JAGYA-ANANDI: What if Jagya and Anandi start feeling for each other again. There are chances that they might come close again since Jagya still has feelings for Anandi.
KNOWING SANCHI: Shiv knows Sanchi very well and he knows that Sanchi's upbringing is completely different from that of Jagya's. They are poles apart and hence not really compatible. Knowing Sanchi so well Shiv should have taken a stand on this union.
KNOWING THE SINGH'S: Shiv knows Jagya and his family very well. He is aware of their family traditions and values and he also knows being a bahu of this family is going to be very difficult for his sister Sanchi who will probably not like some of the orthodox values and things which she will be forced to do.
IRA'S APPREHENSION: Shiv should have thought about his mother Ira and supported her stand as she wasn't ready for this marriage. Ira thought it wouldn't be a good idea to get her only daughter married to a man who is already married twice and divorced. As a son Shiv should have taken care of his mother's feelings and thoughts.
