Do I seem desperate?

It’s this guy on Tinder that I’ve previously had a conversation with on there before I erased the app. Now that I’m back on there we are a match again. Our conversation in the past was me telling him that we went to high school together and seeing if he remembered. Now I want to message him first so bad but I don’t know if I would seem too desperate since I messaged him first last time. Should I message him or wait to see if he’s going to message me. I just don’t want to seem desperate!
