Kinggi - here's my "issue" with you, if you could even call it that: you stress too much. I know its only text I'm seeing from you but I can literally feel the stress and desperation in your posts.
Look. Whether you get women or not you should still relax and take everything day-by-day. The advice people have given you is very good. You just need to re-frame things. For example: instead of going to the gym to get a body for women, you get a good body because you want one! This is just an example of the mindset you should adopt.
Also, I saw some issue with you apologizing for your message. I truly believe a man should never apologize for anything unless its clearly something wrong or offensive. Be secure in the mistakes you make. You will not only become more confident but women will flock to you more and respect you.
Anyway, I'm glad you got the girl's number.
Make sure you have a good time and I'd advise against alcohol. You're better off being sober and making a mistake than risking a drunk version of you taking over. If you can go in sober, make a mistake, and come out with the attitude of trying harder next time - then you would have mastered the game.
This is how confidence is truly gained. Not just by lifting 200 times a day and shit like other men do (though that also works but this kind of confidence is gained from a position of weakness, not strength).
Good luck!
