Why would someone start dating a person of a different race? Shortage of people to date. What? Maybe , because they are attracted to them , see things in their morals, demeanor, personal qualities, values, common interests, that are attractive. The same things I hope you found in your wife, obviously excluding religion and colour. Adopted children that do not look like their parents, don't know where they belong? Nonsense. They have said that 10% of people who think they know who their father is ,DNA shows they are wrong. Lots of divorces have come out of those DNA ancestry sites.
