This scenario is unrealistic though, because I would've made sure I found this out long before she became my "significant other".
A more plausible question would be if I was just getting to know someone who I saw potential in and then found out she has a history of dating whites, would I continue to pursue a relationship with her. And the answer to that is a resounding HELL NO!
Black women who have a consistent history of dating whites almost always hate Black men. Regardless of if it was out of choice or circumstance.
