Search Results: showing him i''m interested

I met her last year in a class we both had and we got to know each other. I didn't realize, but she flirted with me a lot. She always started the conversation, asked how my day was, complimented my shirt, etc. She said we were practically dating. she would have went to prom with me. I liked someone else at the time and I was oblivious, but now I'm interested in her, so here is what's happened since last year:

She followed my insta out of nowhere before school ended
We didn't see each other over summer

She said hi to me again on the first day of school. I asked her how her summer went
She wished me good luck two or three times for games
She always starts the conversation with me
I see her glance at me in the hallways
She quickly brushes her hair as I walk past
She smiles and laughs a lot when talking
Always looks directly into my eyes while talking
She jokes around when talking
She touches her hair while talking to me

she popped up in my Snapchat quick add, so I friended her. She friended back right away to say hi and ask how I was doing. We talked about her sports game and stuff and she replied quickly. She sent cute and silly pics, and she's been one of the first to view all my stories since.

I want to talk to her more and ask her out. I was going to just walk up to her, tell how fun to talk to she is and that I like her a lot, ask her to go out with me..

Unfortunatly, we don't always see each other at school, though when we do we usually talk or wave and stuff, but I don't know if I should just ask her or maybe continue talking and snap chatting her. I started a streak with her the other day, and she mostly sends lics ofnher with a friend, or just her. Sometimes with just her eyes showing or making a silly face.

Usually im the one who snaps her first each day, but she is always the one who starts the conversarions in person. I really feel likes me but I don't know for sure, so what does the situation sound like here?

So Im a senior in high school and I really like this sophomore girl. I met her last year. We had one class together, and I was the only older guy in the class. I only had one friend in the class so I wasn't too social, and she started talking to me around the last few months of the year. I saw her in free sometimes, and she would always say hi, compliment my shirt, flirt a little.
We're both pretty popular in our grades and both pretty good looking.

She said we were practically dating (jokingly) once, stole my phone and took pics on it, insisted on taking pictures with me, even said she would have went to prom with me.

She was sending me these signs, but I am clueless when it comes to girls, so I didn't realize under summer started. I didn't see her over the summer. Our only interaction was liking each other's Insta photos and stuff.

Now, a week or so into school and she continues to show she might like me. I no longer have a class with her, so I only see her after school. She always starts the conversation, walks up to me, says hi. she's never been very shy and doesn't hesitate to talk to me in front of her (or my) friends, She has wished me good luck in sports games multiple times and asked how my day was going, how was my summer, etc. Now that I like her, too, I've been trying to show her that by doing the same. We can never talk for too long, but we say hi (she usually says hi first), talk a little, ask simple questions and stuff. Lately I've seen her flip her hair around or glance my way as I'm walking her way.

I do think she likes me, but I'm not sure how to let her know I feel the same. We have a mutual friend, a girl in my grade, who I think may be a help to find out if she likes me back. So should I have her investigate? And of course I can always just go and ask her. Either way, How should I go about showing her that l like her back? Do you really think she is interested in me and would say yes if I asked her out?
