Let it go, completely.. as you're reading this.. as of this moment.. she doesn't even exist.. she has no role in your life.. there is nobody there.. now..
With that being said.., you should look at what happened.. in the most positive way possible.. because that's the more productive way to look at it.. and the issue here was timing.. you should see what you did wrong.. and learn from it.. for next time.. try to work on your timing..
Also, try and be less confrontational.. girls don't like to be confronted.. It's not like you're going to convince her to go out with you, or stop thinking about some other guy.. So there's no point to it anyway.. all it does is shows that you're pushy, needy, insecure, desperate, and even a little creepy.. So don't do it..
Best,
