Should I feel guilty?

My husbands mother has despised ever since she found out we were getting married and because my husband is white and im mixed blk and white... she vowed to never have anything to do with me or my children, she called me unecesarry names she didnt come to our wedding last june... now Im due to have our first child anyday now (hopefully today:)) mother and son relationship has been very strained since we married, his father and I get on just well he's really excited about becoming a grandfather, but when my husband asked her to be there for the birth of our daughter she told him she would have nothing to do with a multiracial child and to never disgrace her presence with our baby.. this really hurt my husband and his father is really upset that he moved out of the family home into another home that he owns. I feel bad because if we hadnt gotten married a family would have still been a close knit family, I feel like its all my fault.. My husband is clearly upset about the situation
