If you don't want to get over her, then go out with her, show her a good time. Ahh, as friends only! You're not after her, you're not chasing her, you just want to have a blast together like two good friends should.
And then, when she's having a good time, remember how to make her feel this way and do it again and again and again, until she slowly starts to see you as that "funny, smart, and nice unexpectedly" guy. And then after that, who knows what will happen, right? You have a crucial advantage over any competition, you're her friend and close to her. You don't need excuses to take her out and make her feel happy. You can just do it.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
