Taking a second wife

Q: I am a married man. I was in love with a Hindu girl even before my wedding. Now I feel that I need to seperate from my wife and marry the Hindu girl. My wife is ready for a second marriage but the Hindu girl does not want to accept it. She will be a Muslim after the wedding. I dont have much feeling left for my wife and my life is really a problem without the other girl. What should I do? 

Women attending waleemah functions

Q: I have been recently hearing that it is against the sunnah for ladies to attend wedding functions, especially waleemahs. There are certain ideologies that believe women attending wedding functions is haraam altogether, and is not a sunnah: even if the functions are completely segragated and simple!

Kindly advise because I recently attended the weddings of 2 very religious relatives and everything was according to sunnah and within their means. Commenting on another religious Muslims efforts, calling them haraam, propagating women cannot attend waleemahs or wedding functions, isn't this an innovation?
