Do not pay attention to the responses you have received so far, they will no thelp at all. The best advice is to be yourself, be confident in who you are and what you represent. Simply ask the girl if she wants to go out sometime, plain and simple, no hidden agendas. If you are honest and open with her she will respect you more and she will see that you are self confident. If she says no, don;t worry about it, move on as there are many women out there to choose from. Don;t let it hurt your confidence, just keep trying until you find the right one who wants to spend time with you. Believe me, you will get rejected in life so get used to it. Everything will work out fine my friend. Good luck!
