Friendzone her at once, or lie and say you're interested in another girl. Just say you fancy someone else then she should get the hint and stop flirting with you. She could be a socially awkward person who is just trying to be your friend but she is coming across as flirty to you. You need to just be straight with her, and ice weapons are always best.
Pretty much this.
Ulfric Stormcloak; not a racist, not a megalomaniac, not a savage, but a hero with heart & ambition.
All hail to Ulfric you are the High King
In your great honor we drink and we sing
We're the children of Skyrim and we fight all our lives
And when Sovngarde beckons everyone of us dies
We drink to our youth to the days come and gone
For the age of oppression is now nearly done
