How do you know when it's real?

I met this guy 2or3 weeks ago but never got his number due to me being shy and insecure. I feel like he's interested but I don't wanna get hoed by asking for his number. I feel like maybe I'm putting to much thought into everything. So what should I do? How do I know if he's really interested? 🤔
