Racial issues

Ok. So me and my husband has been married a year and half, and his mom has kinda let be known that she has a issue with me being black. At our wedding she hugged and congratulated my husband, but NEVER approached me. I've tried to be nice and understanding. Done anything I could to be accepted, and I finally thought I was until I texted her the good news about expecting and gotten no response just said thank you for checking up on me. That's it. My I told my husband that she doesn't have to see the baby. I'm done with her after that. Am I wrong?
