I can't find a girlfriend

I thought that I could easily find a girl with the help of dating websites, but I'm still single. What do I do?

You can try going to bars and approach girls there. It's the only place that I know where to get a girl's number.

Well, bars and pubs are good for finding somebody, but not every girl goes there to find a relationship. I think that the dating websites you're using are not the best, so you need to change them. As for me, a dating site for geeks works the best, so you can try it too and decide for yourself if it's worth it.
