What’s do I do?

So my mom won’t let me see my bf I’m 17 nearly 18. It’s not because of COVID it’s just that she has been so nasty and said if u want to see him u can find ur own f*ucking way to his house. I don’t even know what brought this on. Should I just ignore her or say something. Me and her don’t have a great relationship she has nearly pushed me over the edge a few times and now I’m just like u can’t say anything I’m old enough to make my own decisions.
