Everyone has a girlfriend but me?

I understand how you feel ! My advice is to talk to girls that have similar interests that you have but don't expect them to be your girlfriend right away. Or hang out at places you like going to and maybe you find a girl hanging out at similar place you like to go to. Also don't rush it with a girl when you finally do get a girl attention. The best chance you have is by communicating with a girl and talking about things not about her looks or right away. Think of a subject or topic that would be interested for you and her to talk about, and don't talk to much at once. You say 2 or 3 sentences and she listen, then she say her 2 or 3 sentences and then you listen to her.
