queer questioning

hey! i have had a crush on this boy for over 3 years but things ended recently. i have always questioned my sexuality but never really acted on anything because i was with him, but now that i’m not i want to explore. i don’t know how to though. i’m really attracted to girls, but i know that’s not the same as being queer. i don’t know how to ask a girl out with saying “i’m not 100% sure if i’m queer” because that seems really shitty. i’m also really shy and don’t know what to do. any feedback would be really helpful :))
