How do i go about this?

Alright so theres this girl ive been into for a few years. One of those years, she knew i liked her but had no idea who i was. Now that weve actually met (we are in highschool) she told her friend (who is also mine) that she met me, and asked if i was still into her. Fast forward a few weeks, i get her number to contact her for a class project, nothing huge. But i come across her twitter one day, and she tweeted "cameron is adorable" then another immediately after with heart eyed emoji. Both were during our class together. Problem is, theres this little indian kid also named cameron in our group. So idk who she is talking about. Then three hours later she tweeted "wheres cameron?" So obviously one of us was on her mind. But i think it makes more sense if its me, because im stereotypically good looking. The other cameron is just a kid.

My question: how do i text this girl? We dont talk much, but if we do its always fun and easy. My main concern is making her feel weird by just texting her out of the blue one day.
