Ok not to be mean but you sound desperate. Dude relax and just let life run it's course, if a girl don't come into your life very soon oh well and if she does cool glad for you. But dude your going at this all wrong, I'm not saying searching for a girl is bad, but you make it sound like it's life or death. Just play it cool, let your swag take over. In other words don't go around asking girls if they'd go out with you cause your chances is none to very none, just hang with your friends, look around at them every once in a while, but just just relax man.
You shouldn't go rushing into a relationship. At this time you don't really need one. If you go out looking for some girl just so you have a girlfriend then you know you will not find the "right one". It may take awhile but there is someone out there for you.
Look where you have common interests. If you are religious, try to meet people from your place of worship, if you are a bodybuilder, look for someone at the gym. Maybe someday you will be standing in line and know the moment you see her, its her. Look in places that you are looking for in her.
