If I were you I'd take her somewhere private where it's just the two of us alone, talk to her and then go for a kiss. If she still wants to talk after that, I'd just keep trying

My Demon revokes any prayer
He's grown contempt for love and hope
He betrays trust, twists truth and fair
Indifference is his way to cope
Engulfing sound of sensations
He quells with voices of despair
And muse of short lived inspirations
Flees at the sight of his cold stare
~Moy Demon - Mihayeel Lermontov~
