Gave my number but no call/text?

So I have been flirting and talking to this guy for a while now that I see at his work and mine. I thought we were both flirting. So I gave him my number. It’s been a couple days and no call or text. But when we see each other it’s the same talking and flirting like nothing happened. Is he being nice and trying not to hurt my feelings and directly say he’s not interested and that’s why he hasn’t called or text? Did I read all the signs wrong?
