If I Ask a Woman to Dance and She Turns Me Down or If I Talk to a Woman and She Ignores Me, It's Because I'm Not Worthwhile or Good Enough For Her.  This irrational belief causes shy men to fear approaching a woman and produces low self-esteem when they are rejected. This fear of being rejected and turned down prevents shy men from making contact with single women.

 If you're turned down for a dance, it doesn't mean that you're not worthwhile or not good enough for her. She just may not feel like dancing at the moment. She may just be tired. She may not even dance. There can be a number of reasons. So don't take it personally. However, what to do in a case like this is to ask her, "Would you like to dance later?" If she says yes, just ask her again later. Even better, just ask her, "Well, can I join you for some conversation?" In the mean time just ask other women to dance.  Also, I might add, a lot of guys get turned down to dance, so don't feel that you're the only man in the world that happens to. It happens to all men, even real good-looking men.  If you approach a woman and try to start up a conversation and she ignores you, don't take that personally either. She just may not feel like talking or being bothered. Perhaps she's tied down to a boyfriend or even married. Also, you just might not be using the proper social skills.
So if she ignores you, move on to the next single woman and you'll find someone who will respond to your advances.
