Ya, that's a valid point. Gopi should be actually be surprised that Ahem remained unmarried ( didn't remarry) all these years. Since he pines for her he is expressing it through anger as shr left him. But wanting to marry Radha is uncalled for. Remember the angry stare he gave her when she doubted vidya's paternity. And I don't think he forgot how Radha instead of being happy for seeing her sister after a long time, bursted out on her for ruining her wedding with Ahem at the temple. He wants to marry such girl?
@bold: Not only that but remember she brought up the paternity issue as a direct result of her trying to deflect attention from herself after the kids told everyone that she hurt Vidya. How could he even possibly consider marrying someone that just hurt his own child???😕
