I like this girl but dont know how to ask her if she bi or gay

I like this girl at school and I'm a girl, I just transfer to the school and like the third day she came up ans sat next to me and she was saying that she liked my outfit and stuff.

lol. I was just staring her because she was mad beautiful.

even...

since that day she will wave at me and then smile at me .

yesturday I saw her and she said whats up, and I was tounge tide, I just mouth the words hi. that was embrassing

I only have one class with her and sometimes in class we stare at each other.

I have no idea if she's gay,bi or curious.

I want to ask her but I dont know how

I think she may be just friendly. Just start off being friends with her ok? Even if she is bi/gay/whatever, if you come on too strong or if you seem desperate, it will just creep her out.

In the past I've found out girls were gay simply by talking about myself or my friends being gay... I dont recommend outing yourself unless you knew she was cool with the whole thing, but maybe mentioning you have gay friends or whatever she'll be comfortable enough to tell you...

START LIKING BOYSSS!!! HAVEN'T I TOLD YOU!!! I JUST DON'T WANT YOU TO GO TO HELL( :
