I matched with my high school crush on tinder and bumble?

I never really talked to him in high school but I've always thought he was cute. We had a few classes together, we're friends on Facebook and follow each other on instagram and he even likes some of my instagram posts (doesn't mean anything I know) but that's the extent of our communication. I swiped right on him on tinder and we matched and I thought "maybe he'll message me" and just assume that he swiped right on every one. Well we just matched on bumble as well. Unlike Tinder, I was the first one to swipe right. Should I message him and what should I message him? It makes me kind of nervous because what if I do message him and it turns out he swiped right on everyone on bumble as well.. thanks in advance!
