I am a half black girl who has had plenty of problems with the families of the white men I date. I am in California where everyone is supposed to be tolerant! So, in a way I kind of know where you are coming from.

As said before you can't make everyone happy and if you are serious about this woman your family should accept it. They do not have to like it or like her but you should not sacrifice your own happiness because of the intolerance of others. You are old enough to not be ruled by your family and you are your own person. Make the choices that will please you in the long run.

With an interracial relationship, someone is always going to have a problem with it and in public people might even glare. You just have to decide if you are ready and able to deal with the consequences.

Also, if it hasn't come up yet, her family could have some big issues with your race too. My uncle on my Father's side was a Black Panther and was very unhappy that his brother married a white woman and had a couple light skinned mulatto kids with her. Most of his family disowned him, yet my Mother's side embraced him with open arms.
