Don't you know who I am?  I am your Wife...to be cherished and admired by you.  
I can't be something I'm not!  I am me...that's who I was born to be...I can't be who you want.  
I'm not a Victorias Model, not a Super Model, not even pretty by any standards.  I've gained some weight, and I have more wrinkles now then when you met me.  
I'm sorry for growing old...sorry for not looking better...sorry for not being who you should be in love with.
I am not sorry being me.  It's who I am.  If you can't see that, then I suppose you'll just have to carry out your miserable life with me....or get a Divorce!
