WHY DO YOU LOVE ME???
There are quite a few ways to answer this question. and its a question I've been plauged with girls asking me.

1. everyone has there own tastes. some people think the sunset is beautiful, some people dream of greatness while watching the grand canyon. some people laugh with their family and friends over a great meal for satisfaction. but I'm different. the sun just blinds me. the grand canyon is a river in a ditch. and friends and family are born to the privileged. i don't like any of it. i like you.

2. there are more beautiful women then you, there are kinder and more gentle souls, there are smarter and richer people, all of these things can change, the most beautiful woman can grow old and ugly, a kind person can become bitter and jealous, smart people cannot compete forever, and money is easily spent. I don't love you for any of these reasons, I fell in love with your beautiful soul, something that will never change or leave you, just stand here by my side and let me show you that i can do the same.
   
   seriously with all the insecure woman's these days they always will counter what you say, so you need to say something that is positive that cannot be counter, comment on something unchangeable or unseen. whether it be within yourself or within them, all other reasons can lead to more insecurity.

Those are really sweet, but the second one can definitely be countered by an already insecure woman. Telling a woman that there are kinder, smarter and more beautiful women out there is something we know, but something we don't like to be told. Saying the last two sentences would probably suffice.
