I'm thinking of divorcing my husband because he can't accept our daughter

My husband is White. I am mixed due to having a White mom and Chinese dad, but I am White passing. But because genetics are weird, our daughter is Asian passing despite being only 1/4 Asian. Our daughter is 7 and he has made comments in a disappointing tone about how she still looks so Asian and how "she isn't growing into her white features". The crazy thing is, our 2 year old son is White passing and he seems to treat our son better than our daughter, obviously because he looks like him. I love my husband but it's so hard to continue to be with someone who can't accept ya'lls child for the way she looks.
