I want to be nice..... But I'm finding it really hard.
It is sad when creatives and writers so badly want to cast a character in a better light and only end up distancing him even farther from the viewers.
Anurag is lower than ever, for no human being would willingly give up his child on another's say so - not if he supposedly loved the child. But I guess in that last part of that sentence reveals a truth even the creatives fail to see... Anurag did not love this child.
While creatives and writers can, and at times do, force a view it has been done so many times now that the viewer no longer trusts their rendition of events. They have discredited their characters, story but far more damaging, their credibility.
While misunderstandings are common, one would think that in such a situation, with Anurag knowing who and what Komolika is, and what she is capable of, he would follow up (if he cared). But nothing. one cannot empathize with such a character - so forget that a viewer could/would sympathize with his situation.
Anurag wanders through live oblivious of what is going on around him and how his actions affect others. He seems not to care as to what his supposed wife does or how her presence poisons and polarizes his family. In short: he deserves a tight slap! (preferably from Maloy again) because maybe, just maybe he will wake up and realize the he himself is the greatest kasautii in this story.
There is no way that the creatives or writers could redeem him - so just give it up and deal with the consequences of what he did.
