I am not sure how right Jagya is to just ask for forgiveness... and leave...
I think he does not want to maintain relationship with gauri any more. Looking at the singhs they want nothing to do with her. So her coming back as a family member is out of the question.
waise its good that he did go and apologize. Gauri did not take a step ahead and accept his apology.
Nor did she take any step of acknowledging that she did bad with Anandi and the Singhs. It was basically revenge for her and thats that.
Not sure if in the future she will reflect back on the letter left by Jagya and return, perhaps she has the baby or is pregnant with the child.
So lets see how CVs shape up the story of Jagya, gauri and Ganga.
I personally cannot see Gauri being a wife of Jagya anymore. Their history is very tainted and sometimes relationships that are broken to such extent cannot be repaired at all.
