Few people agree with me on this, but when asking someone out, getting turned down is a good thing. Without exception.
It is said that "the worst that can happen is they'll say 'no.'" I know from experience that isn't true. Women have laughed in my face, said things like "I'm insulted that you'd think I'd date a loser like you" and "that's my boyfriend over there. Leave me alone or I'll tell him to beat the shit out of you," and other things I don't care to mention; it's a long list. Still, it's a good thing.
If one turns down another's request for a date, it's really nothing personal. The
prima facie reason is that we as humans can't choose who we're attracted to and who we're not attracted to. Beyond that, it takes more that mutual attraction for a relationship to work: compatible personalities and goals, similar interests, skill sets that complement each other... It's true that there are "plenty of fish in the sea," as it were, but compatibility is somewhat rare, and it's worth holding out for.
When someone turns down a date, it's usually because they realize that compatibility isn't there. While rejection hurts, and it may not seem like it at the time, they're actually doing you a favor. If they're not feeling it, but they say "yes" anyway, it will only cause bigger problems down the line.
Being turned down only means you're not what they're looking for. it doesn't mean there's anything wrong with you, or that you're not good enough. Even if a girl actually thinks you're not good enough, or actually tells you you're not good enough, she's still doing you a favor. I mean, would you really want to date such a complete bitch?
I've had 2 dates in 13 years, neither of them lead to anything romantic. I had a hell of a time in Chicago last year, but aside from that, I am a 31 year old unattached male who has no prospects in any way with anyone about anything.
J, you're just starting to figure out who you truly are and what you want out of life. Things are about to become really good for you. I know this from personal experience. I can't promise you that you'll find your soulmate, or multiple soulmates if that's what you're looking for, but you're definitely in for one hell of a fun journey.
