Should I message my colleague? Should a girl shoot her shot?

I work with a man who superswiped me on Bumble at least 8 weeks ago. I left swiped him out of fear of working with him. I work with him and have developed a major crush on him. He deleted / hid his profile since. We spoke properly once. Since he’s seemed nervous when we briefly chat about work. We only really see each other walking the corridors between classes (we are teachers). He says ‘hi!’ to me nearly everytime he’s seen me since I started wearing makeup. I’ve started holding the contact. I know all teachers do this but the eye contact feels intense and prolonged. When we briefly talk about work he stares into my eyes without breaking contact. I’ve never had contact so intense. I am hired day by day in the school and am afraid of missing my opportunity. I am too nervous to approach him in person. I think he may still like me. Would it be weird if I added him on FB and asked him out? Should a girl shoot her shot? What should I do?
