what am i doing wrong? why does no one like me?

I know this sounds like a strange question but i just want to know. Everyone says you can say anything on here so i am going to speak my mind. I dont seem to be able to date anyone. Every time i like someone they never like me back. I know im not really the type of guy that girls like. Im kind of a nerd, and the only sports i play are soccer and track. With the first girl i liked, we kind of just became awkward friends for a while and she never gained any interest in me. Now were friendsish. With a girl i liked very recently, she kind of just stopped talking to me. We were good friends, and then when i started to like her i started to talk to her more and then she just stopped talking to me. I never said anything weird, but she hasnt texted me for a while and at school she doesnt talk to me either. What am i doing wrong? I asked one of my friends and he said that he said he just kind of started talking with the girl he liked and they kind of just ended up together. Obviously that didnt work for me. I know at this point your probably thinking that im a weird loser and your probably right but i just dont have any experience in this field. If you want to know how to move ions around in a quantum computer using different electrical voltages or how magnetars are formed, and how the magnetic field affects the space around them than im your man, but i just dont know anything about relationships. Anyways, if you made it to the end then thank you. Thank you for reading this and i hope you all have a fantastic day!
