As a guy your looks aren't worth much if your confidence is shot (and it usually is after being dumped). That's one of the reasons girls toss themselves at you when you're taken but the moment you're dumped and your self-esteems plummets they vanish.

The way you talk, the way you walk, your whole posture changes. And women have a sixth sense for that.

In my case, I had a girl who had already showed interest in me before (I said no because I was taken) so it was a no brainer. After that it was a matter of not trying too hard. Don't talk a girl trying to get in her pants. Just talk to her, share interests, like you would do with a guy. When you're not trying, you're not afraid to fail and you become more confident. Be open minded. Chances are she'll start throwing signs she's interested and that's when you take her queue.

The most good-looking women I was with in that time were both women I told myself from day 1 "she's out of my league, I'll just enjoy her friendship". I was cool with myself and it just happened eventually. One broke my heart though, and the other was a psycho so...there's that XD

If you still can't do it, just try what most men have done since time immemorial. Lower your standards. It will help to regain your confidence.
