Flirting??...

Soooo me and this guy have been like flirting kind of but neither of us have like really made a move except for when I gave him my number. What do I do??

A little backstory I have known this guy for around two or three years and we really just started talking. I work at a kind of gym and he works out there. We stopped talking for like a week and picked it backup today and both said we missed it. Idk what to do!! He is two years older than me
