For a little over a year I [19m] have my first female friend [18] who I could not imagine having a relationship with. Neither does she, I think.
She has quite a lot of male friends and doesn't like her own gender too much (She does have a few female friends.). She is still hetero and recently broke up with her ex boyfriend.
Another male friend of mine [19] is quite popular with the girls and can flirt with any girl he likes (I am rather shy.). He kinos her very often and that makes me feel sad, as I'd like to have that attention, too. I don't want her to like him more than me. I know that's weird and wrong but I can't do anything about it. 
Is it because I don't have any other female friends and neither much success with girls? What can I do to change it?
