Search Results: asking a guy to prom

When I was a senior in high school (last year), I had to go to my senior year prom by myself. I planned on asking one girl, but she told me she didn't want to go with me. I tried to ask another girl and she said the same thing. I planned on asking a third girl, who was having trouble getting a prom date, and she decided to go by herself knowing that I wanted to go with her. She even called me "ugly and not worth her time". I planned on asking two more girls and they both turned me down too, both saying that I wasn't attractive enough for them. I was depressed and on the brink of crying (which is major because i'm not the type of guy to cry about stuff) and not go to prom at all, but my friend convinced me to go because "it would still be a fun time". Well, when it was time to slow dance, no one wanted to slow dance with me so I sat out and wallowed in self-pity and blamed by genetics (which was the reason why I didn't get a date). To this day, this still affects me. I don't approach girls because I already know that they don't want to date me. Should I let go of this thing that happened to me?

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 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 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. The other day she popped up in my Snapchat quick add, and I don't know if I should add her or not. I don't know if it would be weird to add her without actually asking, even through the quick add feature.

Either way, I'm going to ask her out soon, before our sports seasons end. I'm pretty confident she'll say yes, but not 100%. So, is she interested in me and how should I move forward with this?
