I appreciate your culture and your references to let us know where you were. However, you did break her heart, and in the United States most people do not see Black people marrying white people as colonization. It’s a very old and provincial ideal. But understandable because you’re African. So at this point, there’s really nothing that you can do your a married man now, so leave her alone do not be friends with her and just be polite colleagues within your friend group.
