I am into a childhood friend and I want to hook up with her

I am 24 years old and I am about to graduate college. Yesterday, when I was thinking about my academic journey, I remembered the girl I had a crush on at elementary school when I was a kid. We were classmates for a year and we had a very decent friendship back then. After elementary school, I met her once by coincidence and since then I did not see her. Nonetheless, I still check on her every now and then through texting.

Our last chat was 3 years ago and when I remembered her, I sent her a message. She said that she was happy to hear from me after all this time and we had a good refreshing conversation, talking about our studies and plans for the future. She is studying abroad and she graduates next year.

We kept chatting for three consecutive days and I didn't mind her late messages sometimes, I was just happy to get to talk with her. Even when the conversation seemed to reach its end, I kept it going. I realized that I want more than just that ... I want to see her, to talk to her not just through texting. I want to see what she is like right now, after 12 years. If she is single, I want to hook up with her. After seeing her stories and pictures on social media, she is still that beautiful, stunning and smart girl that I admired since elementary school. But how do I tell her that ? Wouldn't that be as coming on too strong, after just a texting conversation ? We did not see each other for a long time after all.

Realistically, that's asking for too much, since we are not in the same country and plus we are not THAT close. But this is the girl of my dreams If you ask me. She might have changed, that's true. But I want to give it a try. I just want to give her a hint that I am into her and how much she still means to me. I will be eternally grateful to any kind of advice.
