How do you guys deal with this??

I am white and my husband is black, my mother in law is rude in a way that makes her sound polite.. it’s obvious she’s not happy about our marriage and my husband has numerous times stood up for me but all I want is acceptance from my mother in law. She acts as if she deserves more than me, his wife. It bugs me I know that’s his mom but I am his wife he is a grown man he doesn’t and hasn’t lived at home for years now
