u/Elithegullible

Im a 15 year old highschool kid, and after being in highschool I definitely found my type, the more skinny/flat girls. I know its odd, but to me they are a lot more attractive, and I think I found the perfect one. She's quiet, yet has a lot more confidence than she shows when talking to her, and is funny. I first thought I had a chance when we were both at a small version of a homecoming, I guess, and I asked for her number. While at a distance, I saw her smiling whenever she went to text me. I've done small/casual flirting, but not super obvious, but I feel like I can't drag it for too long. Since its a highschool thing she might get tired of it quick. Should I just be direct? Im confused, and am a bit scared of making the first move after I was rejected by another girl some time ago.
