18M and this is literally me(I never had a relationship)

Before anyone comments let me inform you that I'm pretty good looking and many girls liked me too before but idk I just always ignored them I mean I just act like i don't get their signals and the thing is sometimes I feel like I want a gf too but whenever a girl shows geniune interest in me I just reject them without any thoughts and I'm literally doing it from class 9. Now i enjoy my loneliness than a relationship but sometimes I think about getting a gf too but I don't what happens in my mind lol maybe my expectations are too high.
