I am a bisexual girl and I like a girl but idont know if she likes me back or not

Im a girl and bisexual and I like this girl in my form. She doesnt know I like girls. She smiles at me a lot and kind of acts like she fancies me and I think she has guessed I like her but I dont know if she is bisexual or lesbian or straight. We are both awkward people and I really fancy her and pretty much never stop thinking about her but I dont know what to do.

A problem with not knowing someone's sexuality is that you won't know how their reaction would be espicially if they turn out to be straight.. cuz most of the time they won't know what to do in that moment so they sometimes have that instinct to blow you off. (trust me) so try and give hints.. and try and find out her like sexuality or like what shes into, yknow? just becareful since you don't know she could be straight.. I hope I helped.

I can tell that you're in love with her, but what about her ??
I'm not going to tell you , you need to tell her but you need to take you're time to think and get things slowly . The details you writed aren't enough . If you want to know if she like's you first of all :
you'll catch her looking to your lips .
Holding your hands softly and hugging you non stop .
kissing you in the check or ask's if she can kiss you in the lip etc...
If you find all of this in her , then there is 95% that she like you as a girl to a girl and might be bisexual .
