For many, Ahalya might seem to be a weak woman... But I think she's a strong lady, as strong to be possible in her circumstances... Had it been another woman, either she had ignored to believe Greeshma, or ask her to go far away, might have give her a few money, or promised her to take care of her father... But thats max she would have offered... But Ahalya hadn't... She was strong enough to accept her husband's 'crime' as well as taking responsiblity of that... I'm proud of her... I guess she couldn't have done anything more than that...
and to answer ur second question, yeah any other employer would do only that... May be then Greeshma didn't have to face Arjun Mallik, but would she be safe there... How long that money ran... Or how long her father survived in that condition... What will she do after that... Without any relative... Without any money... Without any job... A alone teenage girl with such beauty... Could she survived... Could she possibly b safe... weren't there any more Arjun Mallik around her... I dnt think she could... Here again Ahalya did what she could do for a poor girl, with her best intention, things that turned out wrong wasn't her fault...
