I am in love with a girl and I'd like to know how to keep her.
How do I attract her?
Well, truely, I believe you should try and compliment her. Maybe woe her with any poem or song skills you have. Try not to appear as a nerd. Try and get under her skin, admire her, and if you can get your way into her heart, well my friend.. You have now unleashed the pure male within, and got a free pusillanimous individual. :l Do what Oromis said, and try not to be a fake, otherwise she's not going out with you, she's going out with your imagination.
I hope this helps, Previous.
Plus, try and learn more about her, what she likes, what she looks for in a guy. Dont send out a spy, or you would probably lose her to him if she's gullible, like a blonde.
