Search Results: making promises

This girl i like is a sophmore and im a senior. I know that she had a crush on me last year (she practically told me, more than oncd) and i beleive she still does now.

We talk a lot at at school, little small conversations and stuff but i started Snapchatting about a week ago. she's one of the people i send stuff to the most, and vice versa.

we started a streak and, unless she's actually doing something, she always replies quick. She usually sends pics or her face, sometimes making a kissing face or a peace sign or whatever. Sometimes its just her eyes and sometimes she making a joking face. Sometimes we just send stuff to keep the streak going, but we usually actually have conversations, in which she usually replies quick with long responses.

Now usually when we see each other in school she starts the conversation, whether were alone or with our friends. We both play sports, so were we mostly talk after school. I see her once or twice during the day, usually exchanging a hi or just glancing at each other. Outside of school, We both send each other stuff all the time.

Other signs she may like me:
she promised to come watch my sports game
said i played really well after
made a sign for me
talks to me in front of her friends
sends funny / joking snaps
making eye contact when she passes by
sometimes brushing her hair while talking
she always smiles when we talk

Personally, im sure she likes me. There was a rumour going around a week sgo about her and another guy (a friend of mine.) When i heard this, i panicked and really starred giving her hints i liked her, and nothing has happened between them since.

I think im ready to ask her out. I just want another opinion on how strongly she may or may not have feelings or me, as well as how i should ask her.
