Eloping because of family issues

My FH and I want to get married either late 2020 or early 2021, by that time we will have been together for two years. I am 26 and he is 22 and we are ready to start our lives together but we have had nothing but issues with his side of the family since we’ve been together, his father and step mom treating him like he’s still a child and his mother is a moocher, she only wanted money from him. He’s met my mom and step dad and they like him, but I’m not sure if he’ll ever meet the rest of my moms side of the family mostly because of my racist grandmother and my FH is mixed. He met almost all of my dads side on Christmas Eve, but the only people that spoke to him were my Dad and one of my uncles. My step mom didn’t speak to him at all much less me, including my step sister who was giving him the meanest mug possible the entire time. I am just over family at this point and do not care who is offended when we get married and we don’t invite anyone, that’s just how I feel right now about the situation. Right now I’m feeling having a few friends and his brother and my mom and step dad as witnesses and no one else. He knows how I feel about the situation and he just wants us to be happy. I just needed a place to vent, let me know what you guys think!
