Yes, if he's 'the one'...
It is truly a 'step-up'.
No matter what color, it's always a step-up when a man and woman come together who are right with and for each other.
My sweetheart is Caucasian, yet we 'forget' that we different racial origins. We never really think about it. And when we do, it's the beauty of it doesn't matter to us that makes it a true 'step-up' for both of us.
Okay, enough of the 'flutter'.
Seriously, now-a-days, Black men have just as much prestige as White men in many areas of life. My children are very sucessful and prosperous and they have both married within our race.
Although our family bloodline is African American, American Indian and Jewish (my grandfather and great grandfather were Jewish, my grandmother African American and Indian) we still honor our African heritage and proudly so.
All of the men (my mom's brothers -- all 6 of them) were successful craftsmen and business owners, so it was definitely a step up for the women that they married.
My point, is that it's only a step up when the two people are right for each other, no matter what color...race.
