Should I tell her I'm done chasing her?

I was chasing after a girl but she called me stupid... I want to tell her some things, and I also want to tell her that I m done chasing after her and I don't want anything to do with her, but I don't want to ruin her new years eve by making her feel bad because I really m stupid. I m stupid cause I care about her.
