Family doesn't like BF

Ka

I'm posting in here cause I'm 18 but I have an issue and would like some advice. So me and my bf have been dating for almost a year but we dated for 3 months before this and got back together and have been for 10months now. My family (mainly mom and dad) don't think he's right for me and want me to break up with him. But I really love him and he makes me happy. What should I do?
