Women love it when a guy chases (validation) and starts to feel less confidence when it stops. Its this push pull that will likely get you the girl (if at all). Problem here is she already knows you like her, even willing to risk what you have to 'smash her.'

If I was you, I would laugh everything off that has happened with her and start being unpredictable again like at the beginning. Have fun, smile, joke with her, find out about her life etc etc etc. Being around you needs to be playful, not troublesome.
Then when the time is right and you get your chance, escalate from a kiss to the rest.
You'll only have one chance.
