I agree with everybody!
His statement about never being in a serious relationship with a white girl just states the only thing he likes about white girls is having sex with them. It is doubtful you will change a racist mind that far gone. While this sounds quite rude, I hope his beliefs dies with his generation, the world is far from a bigotry and racist free environment because of people like that.
Lets say you were to stay with him, and have a future with him, would you be willing to sacrifice all your white friends, and maybe even other non black/non white friends, just for him? He certainly won't like it if you lets say hang out with your best guy white friend since kindergarden who you think of as a brother and nothing else, and its unlikely he will give in and allow you to have your ways with who you hang out with.
It's tiring that still some of these individuals who always bring up their "sad" history still to this day. They always blame it on the white people when they don't have an explanation, but are often racist themselves. He, and those other individuals insult their ancestors each time they use them as a excuse for their troubles, what do the generation now know ANYTHING whatsoever about what slavery was like, what it was like to truly suffer? They act as if they were the victims of a sole horrendous crime and need to be pitied upon. There are far more worst events that occurred in history to other ethical races, and I don't see them still bringing the past back and complain.
All in all, do yourself a favor miss lady, and find yourself a man who shares your own beliefs, and won't try to manipulate you with such pitiful excuses.
