Not about sex, just need advice.

I’ve been with my boyfriend for a year now and my mom still doesn’t like him. She’s constantly talking crap about him and we’re always getting into fights because of that. I’ve tried talking about him to her (nice things) but she turns it into something negative. I think what made her not like him is that when we were started dating he dropped me off past my curfew. My curfew is 12:30am and he dropped me off an hour late. No I’m not underage. I’m 24 but I still live with her 🤷🏻‍♀️ She doesn’t know him and she hasn’t even tried to get to know him. I honestly don’t know what else to do. My mother and I have never gotten along. We’ve never had that mother/daughter relationship that most people have so it’s hard to talk to her without her getting mad. Any advice? Ignoring her would probably be best but it’s hard lol
