Biracial couple

I’ve been with my partner for almost 10 years, we have children together and a great relationship but I can’t get past the biracial part. It’s been 10 years of doing everything socially separately because I can’t handle the comments and the staring. After a whole week of arguing because I refused to go to a wedding with him, I just left another social event because I can’t handle people looking at us and talking about us. It’s not in my head I promise. This culture are known to HATE people from my culture and they despise couples like us. I don’t know how to get past this? I’m currently sitting in the car crying because I just left my partner and kids at this event on their own and I know this is the last straw for us. His response was “why are you doing this again?” Which broke my heart but I just can’t do it. I don’t see any other option other than seperating because we will never be accepted or able to live as a normal couple. It’s fine around my people because they’re accepting but his aren’t. Has anyone experienced this? Is there a way to move past it? Do I just need therapy and try to ignore it? I don’t know.
