I can't seem to get a girlfriend?

I can't really get a girlfriend and I try so hard to. None of my friends have girlfriends but when they do, they are very unattractive and dirty or pretty slutty and go around with my other friends. I have been in three relationships in my life. First girl was in 7th grade and lasted 2 weeks. Second girl was in the 9th grade and once again 2 weeks. The third was 11th grade and lasted 6 months. The first girl turned out to be the skank that went around with my friends. The second girl turned out to be uninteresting after a week. The last girl was just a girlfriend but she would always dump me for no reason and I realized she was very immature. I finally just stopped with her. NOW THESE WERE RELATIONSHIPS, I HAVE NEVER BEEN ON A REAL DATE (hung out and had fun)... I just hung out with them at school or my house. No real dates.. Now I am losing my mind. Everytime I see a really good looking girl on Facebook, I try engaging a conversation with them. So many have not replied but some have. They just gave one word replies. The only girls that talk to me are the ones who are (hate to be mean and shallow but) fat. To be exact, I have messaged around 30 girls. 3/4's have not replied over a week and 1/4 replied with one word and just didn't care to know anything about me. I am not looking to go desperate, I never will. I know I am not ugly, I am a really good looking guy. I care a lot about my health and such. I make music and may get a record deal soon and I know I am smart. AND I KNOW I AM FUNNY , I always get told that.... I am confident...but right now...I am losing that confidence and I don't wanna lose my self esteem... I keep wondering if this is fate... Girls just shun me. I don't mean to sound dramatic but this is so weird. I dream everynight about having a girlfriend. It's not the same girl though. I don't know what I can try anymore. I have tried being the caring guy. I have wrote some neat things in my Facebook status before but only fat girls comment. All the good looking girls are just avoiding me. All I can do is ******* cry about it. I always wanted to be like the guys that chased the hot girls on a beach and just have fun. But I CANT! If I ever have a kid I would feel so miserable when I tell him my childhood. I never got to chase girls. I never went on a date with a girl. It's so damn sad to think about.
