I don't think Sumer loves Shagun

If he really does, he would not give up Shagun without much fight. He knows Shagun will never go against the family. History speaks for itself. Shagun left her first love for Sumer. She fought for him and won him from that mistress, She saved the family from Shiv even thought the whole family hates her. Sumer should blindly love her.

If I were him, I would have given it a thought as why she is doing it, rather than just be upset. It does not make sense that when Shagun gives the notice, he would just hate her and support his parents. Especially his step mother who did nothing bad to him.

Just does not make sense..

True,

well urvashi still likes shagun so maybe she'll help her sor things out n i still think tht sumer loves her hes just blinded by triveni n his so called best frend shikha

I also agree that atleast Sumer should have noticed that there was something wrong with Shagun. Instead of taking her side and find out the reason behind her behavior, he went against her. After everything they have gone through to be together and Sumer knows that Shagun can never hurt anyone in his family, he should have trusted her.
