text: okay, you obviously have not had any children of your own yet.  What exactly is the age difference between you and his children?  15 is pretty old.  a 15 year old is no longer a child and they have already formed opinions of their own and could very possibly support themselves if ever needed.  So a 15 year old is a young adult.  My brother is 15.  Its a very delicate stage where they want their parents undivided attention, and they are old enough to know how to get it....His daughter IS "HIS daughter" and has been in his life from day one for 15 years.  He undoughtably loves her, and fathers allow their daughters to manipulate them, even more than their sons for the most part.  This girl may feel as though you are her equal (if you are close in age with her) inturn she will not respect you...@ 15 sometimes you don't even respect your parents let alone the chick your dad's dating.....He is going to take her (and the other children's) side over yours every time, probably forever, if he stays with you....i know this sounds harsh, and it is not meant to offend but I'm just telling you how it is.  And I'm 100% sure it has nothing to do with your race @ all.
