Great job. That is one of the toughest things to do is put yourself out their and face potential rejection. But you did it great job. Its like the quote says "You miss 100 percent of the shots you don't take". You took your shot that's all you can do now the ball is in her court. If she goes out with you awesome but don't expect it. Now just approach every woman you find attractive and ask them out just like that. Most will say no but some will say yes. Its a numbers game the more you approach the more chances you have to meet a awesome woman.
