I think we need to be patient.... She needs to discover her capabilities herself. We saw that when Aradhana felt left out at home, he was the only one who invited her to sit with him. Nothing happens instantly. She she were to fall in love with him instantly, many of us may not sympathethize with her situation. I am not sure if Shatantu will "help" her out in understanding business processes et al but he will definetely support her emotionally and fill her with confidence. To an extent I think it is offensive to want him to guide her in her business. If a man happened to be in Aradhana's position I do not think we would be expecting a woman to guide him professionally. I mean, such an assumption will not come automatically.. something to think about.
I understand it is a bit unrealistic that she is doing so well at every task assigned to her but i think it is sort of necessary for the makers to give her that boost since they want to persist with th eoffice track. If she were to fail, her character in the serial would automatically give up considering she had no confidence to begin with. I think her sucess is the only contravening factor to the underhanded treatment she is recieving from her husband...
