what if he was flirting with other girls on our first meet up?

How did it make you feel? It could just be his personality and have meant nothing to him but if it's made you feel bad then think carefully if you could live with that for the rest of your life before you make a commitment.

I understand how that can be difficult to handle. However he's barely met you then, so he didn't know what he's risking. And believe me guys don't really know how to act. I don't know if you've noticed but we're not all that bright, you know? Sometimes it takes a little bit of feeling things out before we start to act right. So really it leaves things in your hands, which can be good in a way. How do you feel about this guy? Do you think he's worth it? Like the time and effort of getting to know.. If so, you can check how has his behaviors been since ? What kinds of differences have you noticed? Most importantly, how does all that make you feel?
