How to start talking to a talking stage

Weird situation here. We're in a class together. We started texting about a month ago. We sit kind of close to each other (like he sits diagonally from me). We text everyday and EVERYTHING. And we have never talked to each other in real life. What do I do. We're kind of avoiding each other and I don't know how to bring it up to him without possibly ruining what we have. Kind of scared.
