Im black guy and i never had a black girlfriend?

Don't ask me why because i really don't know. All i know is that ever since i been 14 i had 4 white girlfriends, 1 asian, 1 latina, and one white/latina girlfriend. I also have mess with a couple of other girls that are not black. Now that im 23 i just met this Beautiful african american girl. She is 20. But she is really sensitive. Her father was assaulted by white cops when she was 2 years old. Her mother used to work for this Chinese lady that treated her bad. Her brother got shot by some latino gang bangers. And her ex bf who mistreated her left her for a white girl. No offense but shes like a walking stereotype testimonial of a beat down black woman. So because of that she feels blacks should stick together as one. She is not racist she is more insecure. Anyways one time my ex bump into me. She was white. And the girl i like was kind of o.k. But what she think when she finds out i never dated a black girl.
