I don't agree Tamil's logic Charu misused him and yes Thulasi forgave him, he never harmed anyone or tried to kill anyone and neither he suspected thulasi for cheating him.
Thulasi forgave him he was her support when he has vel issue and more. Even good person like Tamil never changed after charu's incident still believing others more than wife.
Person like Prabha who doesn't respect elders, do not hesitate to poison in food to ruin some one, suspect wife's character, torture wife, still doesn't feel guilty about anything. Why should Deepa forgive him, just because she married him?
Serial's should show women more empowered, please do not show women as slaves.
Thulasi and Deepa are submissive already when it comes to their spouses they should learn from Shyamala and Sudha who respect their husbands when they are right at the same time donot hesistate to correct them when they are wrong.
Thanks sri for update.
