Jamaican men dating a white women...?

So ive been dating my jamaican man and he is so amazing. all his friends that r jamaican date white women as well. Why do black men date or marry a white women? i notice it so much. and black women talk badly or give u bad looks. my man says they r jealous cause we white women take the good looking successful black men. i notice these bad looks, i never got bad looks from black women when i dated a white guy. why is that black women get mad or jealous??
