By "independent streak" I would assume he meant, from what he saw, you were very opinionated and might be a "ball buster." Like, you don't take no mess and/or are quick with the tongue to speak your mind. While that could be a commendable thing for most, he might see it as something that his ego can't handle.

Attraction works in two levels—physical and mental/personality. Clearly he thinks your cute but from what he's seen of you in action he sounds to be on the fence on the personality. Not that you have a bad one, but it may be something he can't see himself dealing with in the long run.

You are who you are and you shouldn't be anybody but you, especially when it comes to courtship. So I wouldn't suggest changing or putting on a front for this guy. If his ego can't accept you for who you are then is that really someone you want to be with?

In the event that he does holla I'd take it with a grain of salt, because of your "independent streak" is a too much for him he may just be focusing on the "cute" factor. In that case you'd have to gauge if his intentions where to really get to know you and over your "independent streak" or just him trying to get with a cute chick.
